Answer:
65 cups
Explanation:
In a lilac paint mixture, 20% of the mixture is blue paint, and we have 13 cups of blue paint.
let the total cups be x.
To find the total amount of lilac paint, we can set up the following equation:
20% of x = 13 cups

0.2x = 13
Divide both sides by 0.2.

x = 65
So, there are 65 cups in total of lilac paint.
