A computer manufacturing company has a fixed cost of $7,000. It will cost $700 to produce each computer. The total cost for the company is the sum of its fixed costs and variable costs. Write the total cost, C, as a function of the number of computers produced, x. Then find C(20).
a. C(x) = 7,000 - 700x; C (20) = $ 14,700 b. C(x) = -7,000 + 700x; C (20) = $ 17,700 c. C(x) = -7,000 - 700x0; C (20) = $ 25,000 d. C(x) = 7,000 + 700x; C (20) = $ 21,000
