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. Formulate a function that can be used to determine the cost, in dollars, for a deck with an area of x square feet.

A) f(x) = 529.75x
B) f(x) = 4.75x + 525
C) f(x) = 525x + 4.75
D) f(x) = 4.75x + 525x

Answer 1

f(x) = 4.75x + 525

f(x) = mx + b

4.75 = slope (m)

525 = constant (b)

Answer 2

B

Step-by-step explanation:525 is the constant so no variable should be next to it
