$55 per gallon. 1 gallon covers 100sqft. What is the price per sqft?

marta [7]

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 $100 ft^2$

While the price per gallon is

$55 per gallon

This means that the price per $100 ft^2$ is $55, since 1 gallon cover $100 ft^2$

Therefore, to find the price per square foot, we can write

$\frac{55}{100}=\frac{x}{1}$

WHere x is the price per square foot. Solving for x,

$x=\frac{55}{100}=0.55\$$

So, the price is 0.55$ per square foot.
