9. A calculator vender sets its Price-demand (in dollars) for x calculators by using the model p(x) = 200 - 0.05x. Its factory operating costs are $90,000 plus $20 per calculator. Using this information, find the cost, revenue, and profit functions.

ANSWER: Total Cost = 90,000 + 20x ; Revenue = 200x - .05x2 ; Profit = -0.5x2 + 220x - 90,000

10. Find the marginal cost; marginal revenue; and marginal profit functions.

ANSWER: Marginal Cost = 20 ; Marginal Revenue = 200 - 0.1x ; Marginal Profit = -.1x + 180

BASED ON THE CORRECT ANSWERS ABOVE ANSWER THE FOLLOWING QUESTION! THANKS!

11. Approximate the cost, revenue, and profit for the production of 1701 calculators by using marginal analysis. Compare this to the exact cost, revenue, and profit for the production of 1701 calculators.

THEN, find the marginal average cost, the marginal average revenue, and the marginal average profit.
