Please help! Mr. Smyth uses the function L(x) = 2x^2 to determine the length, in feet, of his landscaping projects. He uses the function W(x) = 5x – 2 to determine the width, in feet, of each project. Which function could Mr. Smyth use to determine the price, P(x), for a rectangular project if he charges $20 per square foot.
Answer choices:
A. P(x) = 10x^2– 4x
B. P(x) = 2x^2+ 5x – 2
C. P(x) = 200x^3– 80x^2
D. P(x) = 40x^2+ 100x – 40

Why is it C? How do you do the work?
