Profit is maximized when Q = 4 and P = $40, with maximum profit = $90.
<u>Explanation:</u>
(a) (i) Marginal cost (MC) = Change in Total cost (TC) by Change in output (Q)
(ii) Total revenue (TR) = Price (P) into Q
(iii) Marginal revenue (MR) = Change in TR by Change in Q
(iv) Profit = TR - TC
Therefore:
Q TC MC P TR MR PROFIT
0 25 60 0 -25
1 40 15 55 55 55 15
2 45 5 50 100 45 55
3 55 10 45 135 35 80
4 70 15 40 160 25 90
5 90 20 35 175 15 85
6 115 25 30 180 5 65
7 145 30 25 175 -5 30
8 180 35 20 160 -15 -20
9 220 40 15 135 -25 -85
10 265 45 10 100 -35 -165
When Q = 4, MR = $25 and MC = $15, so MR > MC. When Q = 5, MR = $15 and MC = $20, so MR < MC. Therefore,
Profit is maximized when Q = 4 and P = $40, with maximum profit = $90.
