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?

Carson is correct.

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

Answer:

Carson is correct.

y = 5x + 25
