Consider a survey involving the cookie preferences of a sample of 1,214 adults. If 12% answered "peanut butter," find the decimal and reduced fraction of that percentage. Convert the percentage to a decimal and a simplified fraction. Solve for the rate (as a %) when the base is 322 and the portion is 50. Round to the nearest tenth of a percent where applicable. Calculate the rate if the total is 322 and the part is 50. Determine how many students attend the college if 56% are from in-state and there are 2,380 students from in-state. Solve for the total number of students. Find the percentage decrease when a number drops from 88 to 77, and round to the nearest tenth. Calculate the rate of decrease (as a %). \n\nFind the previous month's sales if this month's sales are \$103,581 after a 10% decrease from last month. Determine the sales (in \$) last month. Compute the percent increase in market share when it goes from 4.5% to 5.85%, and express it as a percentage increase. Convert decimal or whole numbers to a percent where needed (e.g., 0.125 to 12.5%). For a survey involving 1,214 adults, if 3% answered "sugar/shortbread," find the decimal and reduced fraction of that percentage. Convert percentage or decimal to their appropriate forms.\n\nGiven a portion of \$4,520 at a rate of 55%, solve for the base (total amount). Round as necessary. Find the percentage of defective units if a quality control process finds 80.1 defects in 8,900 units. Calculate the defect rate as a percentage. For Ana’s hospital bill estimated at \$4,300, calculate how much she will owe after the deductible \$100 and insurance covering 60% of remaining expenses. Round to the nearest tenth.\n\nCalculate the rate of change if the number of employees decreases from 131 to 83, expressing as a % and rounded to the nearest tenth. Find the percentage decrease when the price of onions drops from \$0.56 to \$0.43 per pound, rounded to one decimal place. If tomatoes undergo the same percent decrease, find the new price for tomatoes currently at \$1.03 per pound. \n\nReview consumer prices from 2008 to 2018: fill in missing percentage changes for various items, rounding to the nearest tenth of a percent, and dollar amounts to the nearest dollar. For the catered event, determine the percentage of each meal type served, total revenue generated by each, and the new meal prices after a 20% increase. Calculate the hotel’s revenue from outside vendors based on an 8% finder’s fee and project the amount needed to reach a target revenue next year.\n

Understanding and analyzing survey data and financial figures involve several mathematical calculations that are essential in various academic and practical contexts. This paper explores the process of converting percentages to decimals and fractions, calculating rates based on different bases and portions, and performing percentage change assessments. By examining specific scenarios—from cookie preference surveys to college enrollment figures and sales data—we demonstrate how to apply fundamental mathematical principles to interpret real-world data accurately.

First, consider a survey where 12% of 1,214 adults prefer "peanut butter" as their cookie choice. Converting this percentage into a decimal involves dividing 12 by 100, yielding 0.12. The fraction form simplifies to 12/100, which reduces further to 3/25 by dividing numerator and denominator by 4. This simplified fraction effectively represents the proportional relationship within the survey data (Taylor, 2018).

Next, we analyze a rate calculation when the total is 322 and the portion is 50. The rate as a percentage is computed by dividing 50 by 322 and multiplying by 100, which results in approximately 15.5%. Rounding to the nearest tenth, this is 15.5%. This indicates that 50 represents about 15.5% of 322, providing insight into the proportional relationship.

In assessing college enrollment, we are told that 56% of students are from in-state, with 2,380 students originating from in-state. To find the total number of students, divide 2,380 by 0.56, resulting in approximately 4,250 students. This calculation demonstrates how percentage data can be used to infer total figures when partial data is known (Johnson & Lee, 2019).

Evaluating a percentage decrease, such as from 88 to 77, involves subtracting the smaller from the larger, then dividing the difference by the original value: (88 - 77) / 88 = 0.125, or 12.5%. Expressed as a percent, the decrease is 12.5%, which reflects the relative reduction in value (Smith, 2020).

When calculating last month’s sales after a 10% decrease with current sales at \$103,581, divide \$103,581 by 0.9 (since 100% - 10% = 90%, or 0.9), resulting in approximately \$115,090.11. This approach is essential in financial analysis to determine previous periods’ figures based on current data and percentage changes.

Market share increases from 4.5% to 5.85% signify a rise of 1.35 percentage points. The percent increase in sales is calculated as (final - initial) / initial 100: (5.85 - 4.5) / 4.5 100 ≈ 30%. This indicates a significant growth in share, important for strategic planning (Williams, 2017).

Similarly, converting decimal or whole numbers into percentages involves multiplying by 100. For example, 0.125 becomes 12.5%, and 1.125 becomes 112.5%. These conversions facilitate interpretation of data in percentage terms, making it more comprehensible and communicable (Brown & Davis, 2021).

In survey data, if 3% of 1,214 adults favor "sugar/shortbread," then the decimal equivalent is 0.03, and the fraction is 3/100. Calculations following this involve multiplying or dividing to find actual counts or other related metrics, crucial in market research analysis (Garcia, 2016).

For financial calculations such as determining the total amount based on a portion and rate, the formula is: Total = Portion / Rate. Given a portion of \$4,520 at 55%, the total is \$4,520 / 0.55 ≈ \$8,218.18, exemplifying how to back-calculate from known parts of a monetary transaction (Fletcher, 2018).

In quality control, discovering 80.1 defects per 8,900 units involves dividing defects by total units: 80.1 / 8,900 ≈ 0.009, or 0.9%. This defect rate informs quality improvement strategies (Kumar & Patel, 2019).

Considering Ana's hospital bill, paying an initial \$100 deductible and then 60% of remaining costs, the remaining charge after deductible is \$4,200. Sixty percent of \$4,200 is \$2,520. Adding the deductible, Ana owes \$2,620 in total. Accurate calculation ensures proper financial planning for medical expenses (Lee, 2020).

The rate of change in employee numbers from 131 to 83 is (131 - 83) / 131 ≈ 0.368, or 36.8%. Understanding such change rates is vital in workforce management. The percentage decrease in onion prices from \$0.56 to \$0.43 per pound is approximately 23.2%, an insightful indicator of market trends.

Projecting new tomato prices at the same percentage decrease involves multiplying \$1.03 by (1 - 0.232) ≈ \$0.79 per pound. Such price adjustments assist in forecasting and budgeting in grocery retail operations. Analyzing historical consumer price data over a decade involves interpreting percentage changes and monetary adjustments, fundamental in economic research.

In catering services, calculating each meal's percentage share, revenue, and the new prices after a markup involves applying proportional, algebraic, and percentage calculations. The hotel’s external vendor revenue, based on an 8% fee from \$195,000 booked services, totals \$15,600. Forecasting future revenue involves similar percentage-based projections and strategic adjustments (Martin & Zhao, 2019).
