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

An apple orchard has an average yield of 38 bushels of apples/tree if tree density is 21 trees/acre. For each unit increase in tree density, the yield decreases by 3 bushels. Letting x denote the number of trees beyond 21/acre, find a function in x that gives the yield of apples.
