(1 pt) The total profit (in dollars) from the sale of charcoal grills is
P(x)=30x-0.3x^2-215
(A) Find the average profit per grill if 40 grills are produced.
Ave. profit =
Find the marginal average profit at a production level of 40 grills.
(B) Marginal average profit =

Find the marginal average profit at a production level of 40 grills.
(B) Marginal average profit =
Use the results from parts (A) and (B) to estimate the average profit per grill if 41 grills are produced.
(C) Estimated average profit =
(A)
Ave.profit = P(40)/40=505/40=12.625
(B)
MP(x)=30-0.6x
Marginal average profit =MP(40)=30-0.6×40=6
(C) Estimated average profit =MP(40)=6
再问： B,C是错的
再答： 可能是错的，主要是一些英文单词有些不理解，你问问其它人吧
