Please I need help. This is an exercise that has all this parts and I do not really know how to do it. If you please can put separately just the answers I'll be very thankful. Thank u so much !

Below you are given the price p (q ) at which q units of a particular commodity can be sold and the total cost C (q ) of producing the q units. P(q) = 48 - 39; C(q) =392+49 +27 Part 1 out of 7 (a) Find the revenue function R (q ) and the profit function P(q). The revenue function is R (q) = 0 The profit function is P(q) = Part 2 out of 7 (a) Find the marginal revenue R '(q ), and marginal cost C'(q). The marginal revenue function is R '(q ) - The marginal cost function is C'(q ) - Part 4 out of 7 (a) Determine the level of production q where P(q ) is maximized. P (q ) is maximized when units are produced. Round to the nearest hundredth. Part 5 out of 7 (b) Find the average cost A (q ) C(q) The average cost function is A (q ) = Part 7 out of 7 (b) Determine the level of production q at which A (q ) is minimized. A (q ) is minimized when units are produced. Round your answer to the nearest unit
