Consider The Hypothetical Demand Schedule For Tam ✓ Solved

Consider the following hypothetical demand schedule for "Tammy

Consider the following hypothetical demand schedule for "Tammy Fay" brand Mascara: Price per pound: $0, $6, $12, $18, $24, $30, $36. Quantity demanded: 600 lbs, 500 lbs, 400 lbs, 300 lbs, 200 lbs, 100 lbs, 0 lbs. Based on this demand schedule, use Excel to set up a graph of the demand curve and also the corresponding total revenue curve (use two separate graphs for this, in both cases with quantities on the horizontal axis). In this same Excel sheet, also calculate the price elasticity of demand for each price range using the midpoints formula.

Suppose that the demand for Cod Liver Oil (CLO) can be written QD = 5000 - 2P (the inverse demand curve for CLO is P = 2500 - 0.5QD), where P is the price per ton (in dollars) of CLO and QD is the quantity demanded (in tons) in a period. Based on this information, create an Excel sheet which: (1) Sets up scatterplots of the demand curve and (ii) the corresponding total revenue curve for this market (in two separate diagrams). (2) Calculate price elasticity of demand using the point elasticity formula at the following amounts of CLO along this demand curve: QD=4000, QD=2500, QD=1000. Also, calculate total revenue from sales in this market at each of these quantities: QD=4000, QD=2500, QD=1000.

The demand schedule for "Tammy Fay" mascara provides a clear insight into the relationship between price and quantity demanded. Market analysis requires an understanding of demand curves, total revenue curves, and the price elasticity of demand, which informs businesses about consumer responsiveness to price changes.

To begin with, the demand schedule for "Tammy Fay" mascara shows how quantity demanded decreases as the price increases. The data set is as follows: At a price of $0, the quantity demanded is 600 lbs; at $6, it decreases to 500 lbs; at $12, it is 400 lbs; at $18, it falls to 300 lbs; at $24, the quantity demanded is 200 lbs; at $30, it is 100 lbs; and finally, at $36, the demand drops to zero. By utilizing Excel, one can create a demand curve graph, plotting price on the vertical axis and quantity demanded on the horizontal axis.

To create the total revenue curve, total revenue can be calculated by multiplying the price per pound by the quantity demanded for each corresponding price point. For example:

  • At $0: Total Revenue = $0 * 600 = $0
  • At $6: Total Revenue = $6 * 500 = $3000
  • At $12: Total Revenue = $12 * 400 = $4800
  • At $18: Total Revenue = $18 * 300 = $5400
  • At $24: Total Revenue = $24 * 200 = $4800
  • At $30: Total Revenue = $30 * 100 = $3000
  • At $36: Total Revenue = $36 * 0 = $0

This information can also be plotted in Excel to illustrate how total revenue changes with respect to price changes. The results will show a peak revenue at a specific price point, indicating the most optimal price that maximizes total revenue.

Next, the price elasticity of demand can be calculated using the midpoint formula, which is defined as:

Price Elasticity of Demand (Ed) = (ΔQ / [(Q1 + Q2) / 2]) / (ΔP / [(P1 + P2) / 2])

Where ΔQ represents the change in quantity demanded and ΔP represents the change in price. For each price range, the elasticity of demand must be computed. This involves determining the change in quantity demanded and the corresponding change in price:

Price Elasticity Computations for "Tammy Fay" Mascara

  • From $0 to $6:
  • ΔQ = 500 - 600 = -100
  • ΔP = 6 - 0 = 6
  • Ed = (-100 / 550) / (6 / 3) = -0.0909
  • From $6 to $12:
  • ΔQ = 400 - 500 = -100
  • ΔP = 12 - 6 = 6
  • Ed = (-100 / 450) / (6 / 9) = -0.0667
  • From $12 to $18:
  • ΔQ = 300 - 400 = -100
  • ΔP = 18 - 12 = 6
  • Ed = (-100 / 350) / (6 / 15) = -0.0714
  • From $18 to $24:
  • ΔQ = 200 - 300 = -100
  • ΔP = 24 - 18 = 6
  • Ed = (-100 / 250) / (6 / 21) = -0.0714
  • From $24 to $30:
  • ΔQ = 100 - 200 = -100
  • ΔP = 30 - 24 = 6
  • Ed = (-100 / 150) / (6 / 27) = -0.0867
  • From $30 to $36:
  • ΔQ = 0 - 100 = -100
  • ΔP = 36 - 30 = 6
  • Ed = (-100 / 50) / (6 / 33) = -0.12

Moving on, to analyze the demand for Cod Liver Oil (CLO) using the equation QD = 5000 - 2P, we can calculate the price when given certain quantities. The corresponding inverse demand curve is P = 2500 - 0.5QD. This can be applied to find the total revenue and elasticity of demand at specified quantities as follows:

Elasticity and Revenue for Cod Liver Oil

To calculate the values:

  • For QD = 4000:
  • P = 2500 - 0.5(4000) = $1000
  • Total Revenue = Price Quantity = $1000 4000 = $4,000,000
  • For QD = 2500:
  • P = 2500 - 0.5(2500) = $1250
  • Total Revenue = $1250 * 2500 = $3,125,000
  • For QD = 1000:
  • P = 2500 - 0.5(1000) = $2000
  • Total Revenue = $2000 * 1000 = $2,000,000

Then, using the point elasticity formula, we can calculate the elasticity of demand at the specified points:

  • For QD = 4000:
  • Ed = (−2 QD / P) = (−2 4000 / 1000) = -8
  • For QD = 2500:
  • Ed = (−2 * 2500 / 1250) = -4
  • For QD = 1000:
  • Ed = (−2 * 1000 / 2000) = -1

In conclusion, analyzing both "Tammy Fay" mascara and Cod Liver Oil (CLO) using demand schedules, revenue calculations, and elasticity provides invaluable insights for businesses.
