An apple orchard has an average yield of 36 bushels of apples/tree if tree density is 21 trees/acre. For each unit increase in tree density, the yield decreases by 2 bushels. Letting x denote the number of trees beyond 21/acre, find a function in x that gives the yield of apples. ?
A. f(x) = (21 + x)(36 + 2x) B. f(x) = 2(21 + x)(36 - x) C. f(x) = 2(21 - x)(36 - 2x) D. f(x) = (21 - x)(36 + 2x) E. f(x) = (21 + x)(36 - 2x)
