Question

Carson’s estimate for the cost of tiling his bathroom floor is $25 plus $5 per square foot. He says that he can model the cost with a linear function. Is Carson correct? Why or why not?

Answer 1

Let's write the variables first.
Let:
x = number of square feet of the bathroom floor.
y = total cost in $.
The function that best suits the problem is:
y = 5x + 25
