It is recommended that one fire extinguisher be available for every 4,520 square feet in a building. Write and solve an equation
1 answer:
Answer:
There are 19.5 extinguishers needed.
Step-by-step explanation:
Given that,
One fire extinguisher be available for every 4,520 square feet in a building.
We need to find the value of x if the number of fire extinguishers needed for a building that has 88,140 square feet.
x = (Area of building)/(Area of one fire extinguisher)
So,
So, there are 19.5 extinguishers needed.
