Solve the problem.Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $10,000 the first year that the dealer opened and $62,500 five years after opening. Let x = 0 represent the first year. (a) Find the equation giving yearly sales y. Write your answer in slope-intercept form. (b) Use your equation from part (a) to estimate sales in the third year.
A. (a) y = 52,500x + 10,000; (b) $115,000 B. (a) y = 10,500x + 62,500; (b) $83,500 C. (a) y = 52,500x + 62,500; (b) $167,500 D. (a) y = 10,500x + 10,000; (b) $31,000
