Floor tiles are 12 inches by 12 inches. How many tiles are needed
to tile a floor that is 36 feet by 15 feet?
Which expression can be used to solve this problem?

540 tiles are needed to tile a floor that is 36 feet by 15 feet.

Step-by-step explanation: You need to find the area of the floor. 36x15 is 540.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
