the price is 0.55$ per square foot
Step-by-step explanation:
We can solve the problem by using the rule of three.
In fact, we know that:
1 gallon covers an area of ![100 ft^2](https://tex.z-dn.net/?f=100%20ft%5E2)
While the price per gallon is
$55 per gallon
This means that the price per
is $55, since 1 gallon cover ![100 ft^2](https://tex.z-dn.net/?f=100%20ft%5E2)
Therefore, to find the price per square foot, we can write
![\frac{55}{100}=\frac{x}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B55%7D%7B100%7D%3D%5Cfrac%7Bx%7D%7B1%7D)
WHere x is the price per square foot. Solving for x,
![x=\frac{55}{100}=0.55\$](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B55%7D%7B100%7D%3D0.55%5C%24)
So, the price is 0.55$ per square foot.
