Answer:
Explanation:
You can use proportions to solve this.
You are paying $116.64 for 3 gallons of paint, so you could write this as:
\frac{116.64}{3}
Since the question is asking for price PER CUP, you want to convert 3 gallons to cups. 3 gallons = 48 cups. So now you can rewrite this as:
\frac{116.64}{48 cups}
In order to find the cost per cup, you can set up a proportion that solves for the price, x
\frac{116.64}{48 cups} = \frac{x}{1 cup}
Solve for x by cross multiplying:
48x = 116.64
x = $2.43
It costs $2.43 per cup of paint
