There are 48 inches in 4 feet, which is represented by the equation 4y = 48x. Determine the number of inches per foot.
To determine the number of inches per foot, we can rearrange the equation 4y = 48x to solve for y (inches per foot).
Dividing both sides of the equation by 4:
y = 48x / 4
y = 12x
Therefore, there are 12 inches per foot.
