Problema Solution
A hallway measuring 90 feet x 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot. How much cleaning solution is required to clean the hallway?
Answer provided by our tutors
First we need to find the area A of the hallway
A = 90*7
A = 630 ft^2
Let x represent the amount of cleaning solution needed for the hallway
x = (1/2)*A
x = (1/2)*630
x = 315 oz
315 oz of cleaning solution is required to clean the hallway.
