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
 
 Carson is correct.
 y = 5x + 25

Idon’t feel like doing the math but you need to do 2.24 divided by 7
