Paper For Above instruction

In this problem set, we explore the financial aspects of buying and selling two types of cars: compact and mid-sized. We develop algebraic expressions to model revenue, costs, and profit, enabling a comprehensive understanding of the company's financial operations.

Revenue Modeling:

Suppose the company sells compact cars at $23,000 each and mid-sized cars at $35,000 each. Let x represent the number of compact cars sold in a month, and y represent mid-sized cars similarly. The revenue generated from selling compact cars can be expressed as a monomial:

Revenue from compact cars: Rcompact(x) = 23,000x

Similarly, revenue from mid-sized cars is:

Rmid(y) = 35,000y

The total revenue from both types of cars per month is the sum of these individual revenues, which forms a polynomial expression:

Total Revenue: Rtotal(x,y) = 23,000x + 35,000y

Cost Modeling:

The purchasing costs per car are given as $11,000 for each compact car and $25,000 for each mid-sized car. Thus, the cost to buy x compact cars is:

Ccompact(x) = 11,000x

And the cost for y mid-sized cars is:

Cmid(y) = 25,000y

The company also incurs fixed expenses such as rent, salaries, and utilities, totaling $117,275. The total cost expression combines variable costs for purchasing cars and fixed expenses:

Total Cost: Ctotal(x,y) = 11,000x + 25,000y + 117,275

Profit Calculation:

Profit is obtained by subtracting total costs from total revenue. The polynomial expression for profit, P(x,y), in simplest form, is:

P(x,y) = Rtotal(x,y) - Ctotal(x,y)

which simplifies to:

P(x,y) = (23,000x + 35,000y) - (11,000x + 25,000y + 117,275)

= (23,000x - 11,000x) + (35,000y - 25,000y) - 117,275

= 12,000x + 10,000y - 117,275

Calculations for Specific Scenarios:

(i) For 20 compact and 15 mid-sized cars:

  • Revenue:

    R = 23,00020 + 35,00015 = 460,000 + 525,000 = $985,000

  • Cost:

    C = 11,00020 + 25,00015 + 117,275 = 220,000 + 375,000 + 117,275 = $712,275

  • Profit:

    P = R - C = 985,000 - 712,275 = $272,725

(ii) For only mid-sized cars, to break even (profit = 0):

Set the profit equation to zero and solve for y:

0 = 12,000x + 10,000y - 117,275

Since only mid-sized cars are bought and sold (x=0), then:

0 = 10,000y - 117,275

=> y = 117,275 / 10,000 ≈ 11.7275

Therefore, the company must sell approximately 12 mid-sized cars in a month to break even.
