A computer manufacturing company has a fixed cost of $10,000. It will cost $1,000 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(30).
a. C(x) = 10,000 – 1,000x; C (30) = $ 30,000
b. C(x) = -10,000 + 1,000x; C (30) = $ 10,000
c. C(x) = -10,000 – 1,000x; C (30) = $ 27,000
d. C(x) = 10,000 + 1,000x; C (30) = $ 40,000
d. C(x) = 10,000 + 1,000x; C (30) = $ 40,000
