Question 456479: Write a cost function for the problem. Assume that the relationship is linear.
Fixed cost, $ 100; 5 items cost $ 1790 to produce

A)

C(x) = 676x + 100

B)

C(x) = 338x + 100

C)

C(x) = 338x + 1790

D)

C(x) = 676x + 1790

Since the fixed cost is $100, we know that if we make zero items (x = 0), then the cost is $100. Hence, only one of A or B is correct. If we replace x = 5 into both cost functions, we see that answer choice B satisfies C(5) = 1790. So choice B is correct.
