Solve the problem.Marty's Tee Shirt & Jacket Company is to produce a new line of jackets with an embroidery of a Great Pyrenees dog on the front. There are fixed costs of $670 to set up for production, and variable costs of $39 per jacket. Write an equation that can be used to determine the total cost, C(x), encountered by Marty's Company in producing x jackets.
A. C(x) = 670x + 39 B. C(x) = 670 - 39x C. C(x) = (670 + 39) x D. C(x) = 670 + 39x
