Find the marginal prot function if cost and revenue are given by 000 = 155 + 0.7x and R00 = 7x - 0.04x2. E> P'(x)= |:| The prot (in dollars) from the sale of x lawn mowers is P(x) = 90x - 0.09:3 - 750. (A) Find the average prot per mower if 30 mowers are produced. (B) Find the marginal average prot at a production level of 30 mowers, and interpret the results. (0) Use the results from parts (A) and (B) to estimate the average prot per mower if 31 mowers are produced. (E) (A) If 30 mowers are produced, the average prot per mower is $|:|. (Round to the nearest cent as needed.) Find the average cost function if cost and revenue are given by C(x) = 114 + 5.1): and F100 = 6x - 0.08x2. The average cost function is C(x) = D. Find the profit function if cost and revenue are given by (30:) = 129 + 6.6x and R00 = 6x - 0.08x2. The prot function is P(x) = D
