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 $600 to set up for production, and variable costs of $41 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) = 600 - 41x B. C(x) = 600 + 41x C. C(x) = 600x + 41 D. C(x) = (600 + 41) x
