It is recommended that one fire extinguishers be available for every 6,000 s I are feet in a building. Write and solve the equation to determine X, the number of fire extinguishers needed for a building that has 135,000 square feet. Show your work

For every 6000 square feet in a building, there is one fire extinguisher.

So for 135000 square feet, the equation is like direct proportion (because the more the square feet, the more fire extinguishers needed).

1 : 6000

x : 135000

Multiply x with 6000, and 1 with 135000.

So, the result is:

6000x = 135000

x = 135000/6000

x = 22.5
