Let’s assume that the old clunker you have been driving needs $500 in repairs in order to pass an annual car inspection. You are
considering buying a new car, and you contact car dealers and banks to determine the best deal you can get on a car loan. Assume two different scenarios: (a) The lowest interest rate you find on a five-year car loan is 10 percent, and the annual rate of inflation for the next five years will be 9 percent. (b) The lowest interest rate you can find on a five-year car loan is 6 percent, and the annual rate of inflation for the next five years will be 1 percent. Question: Under which scenario—(a) or (b)—will you pay less, in real income, for your car loan?

Answer:
1. 20 units
2. $600
Explanation:
1.
MC = 4q
Price, P = $80
For maximizing profits,
Marginal cost = Price of the commodity
4q = 80
q = 20 units
= 200 + 800
= 1,000
2. Profit = Total revenue - Total cost
= (Price × Quantity) - TC
= (80 × 20) - $1,000
= $1,600 - $1,000
= $600
3. We know that the firm in the short run will be produce at a point where total revenue is greater than the total variable cost
Average variable cost = variable cost ÷ quantity
= 2Q
MC = 4Q
Here, MC is greater than AVC at any given point.
so in the short run firm will producing short run positive profit.
