Answer and Explanation:
a and b. The average total cost and the marginal cost is shown below:
As we know that
Average cost is
= Total cost ÷ total number of customer loads
And, the Marginal cost is
= Additional total cost incurred for extra units generated
So based on this, the marginal cost and the average total cost are as follows
Customer load level Total cost Average cost Marginal cost
0 $27
1 $30 $30 ÷ 1 = 30 30 - 27 = 3
2 $32 $32 ÷ 2 = 16 32 - 30 = 2
3 $35 $35 ÷ 3 = 11.67 35 - 32 = 3
4 $38 $38 ÷ 4 = 9.5 38 - 35 = 3
5 $42 $42 ÷ 5 = 8.4 42 - 38 = 4
6 $48 $48 ÷ 6 = 8 48 - 42 = 6
7 $57 $57 ÷ 7 = 8.14 57 - 48 = 9
8 $68 $68 ÷ 8 = 8.5 68 - 57 = 11
c. Now the customer loan you want is
As we know that
Profit = Marginal revenue - marginal cost
And, as we can see that at marginal cost 9 we can load 7 customers so the 7 customers would be wanted
