1 The graphs of the revenue and cost functions for the production and sale of x units are shown below. The cost function is the straight line and the revenue function is the curve. 70000 + 60000+ + 50000 40000 + + 30000+ + 20000+ 10000 + 0 100 200 300 400 500 600 700 800 900 1000 X (a) Use the graph to estimate the production level x that maximizes the profit. (b) Make the points (x,C(x)) and (x, R(x)) on the graphs of the cost and revenue function corresponding to the value of x hat maximizes profit. (c) What is the maximum profit? (d) If the fixed costs increase by 25 dollars, should the production level be raised, lowered, or remain the same to maximize profit? Explain in terms of the graph. 1 The graphs of the revenue and cost functions for the production and sale of x units are shown below.
