A small machine shop manufactures drill bits used in the petroleum industry. The shop manager estimates that the total daily cost (in dollars) of producing x bits is:

C(x) = 1000+25x - 0.1x²

(a) Find Average cost (AC) and Marginal cost (MC) when Q=10.

(b) Further, if the selling price of a unit is2x² + 9, find the Average Revenue (AR) and Marginal Revenue (MR).

(c) Calculate Average Profit (AP) and Marginal Profit (MR).
