Please look this over: If you can let me know if I have given the correct response:

Assume that the following has a linear cost function. Find the costfunction, C(x), revenuefunction, R(x), and profitfunction, P(x), where x is the number of items produced(or sold).

Fixed Cost = $300

Marginal Cost = $18

Item Cost = 30

C(x) = 30(x)+300

R(x) = 30*100

P(x) = Revenue - cost = 300-30
