Question 166027: can someone help me with this problem:
Write a cost function for the problem. Assume that the relationship is linear.
Marginal cost, $40; 70 items cost $3800 to produce
a. C(x) = 14x + 3800
b. C(x) = 40x + 1000
c. C(x) = 40x + 3800
d. C(x) = 14x + 1000

You can put this solution on YOUR website!
Marginal cost= cost of one additional piece=$40
so 70 pieces normally costs 70*40=2800
3800-2800=1000 is the initial cost so cost function is:
C(x) = 40x + 1000
