Solve the problem.Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $6500 the first year that the dealer opened and $68,500 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 = 12,400x + 68,500; (b) $93,300 B. (a) y = 62,000x + 68,500; (b) $192,500 C. (a) y = 12,400x + 6500; (b) $31,300 D. (a) y = 62,000x + 6500; (b) $130,500
