Solve the problem.Assume that the annual sales of a small manufacturer can be modeled by a linear function and that sales were $10,500 in 1982 and $54,000 in 1987. Let x = 0 represent 1982 and f(x) represent annual sales, and write a formula for f(x).
A. f(x) = 8700x + 10,500 B. f(x) = 43,500x + 54,000 C. f(x) = 8700x + 54,000 D. f(x) = 43,500x + 10,500
