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 $590 to set up for production, and variable costs of $46 per jacket. Write a linear equation that can be used to determine the total cost, y, encountered by Marty's Company in producing x jackets.
A. y = 590 - 46x B. y = 46x - 590 C. y = 590 + 46x D. y = 590x + 46
