Question

Harris is building a deck around his pool. His contractor charges $525 for labor plus an additional $4.75 per square foot for materials. Which equation can be used to determine the cost, in dollars, for a deck with an area of x square feet?

Answer 1

The equation used is f(x) = 525 + 4.75x.

Answer 2

525 + 4.75x

Explanation:

Total cost = (Labor cost) + (price of the material)

→ Price of the material = (Price per square foot of the material)(area)

→ Total cost = 525 + (4.75)(x)
