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.
(b) In the long run, new firms will enter the market by being attracted by positive short run profit. Therefore in long run, demand for individual firm will decrease, price for individual firm will decrease and profit will decrease until each existing firm earns zero economic profit.

Answer:
The answer is $26,900
Explanation:
The interest payment on $175,000 principal is:
8% x $175,000
$14,000
At the end of each year, both principal and interest payment will be paid.
The total payment for December 31, Year 1 is $40,900. Meaning this contains both the principal and interest payment.
So in the light of the above, the principal out of this money will be:
Total amount paid minus interest paid.
$40,900 - $14,000
=$26,900
