Write an expression for the number of gallons of water in any number of cubic inches of water.
Answer to Problem 31IP
Explanation of Solution
Given:
One gallon of water is equal to 231 cubic inches.
In order to write an expression for the number of gallons of water in any number of cubic inches of water, let c be the number of cubic inches, then 231 cubic inches of water goes into one gallon, so divide the number of cubic inches by 231 to find the gallons as shown below:
So, the expression for the number of gallons of water in any number of cubic inches of water is
