Answer:
40 ounces.
Step-by-step explanation:
We are going to find this by using ratios.
Given that we have 4 ounces of red paint, 5 ounces of blue paint, and 2 ounces of white paint. The total ounces of paint in a shade of purple is 4 + 5 + 2 = 11.
The fraction of the paint that is blue is thus ounce of blue paint/total ounce of paint = 5/11
So, the number of ounces of blue paint are needed to make an 88 ounce batch of paint is fraction of blue paint × 88 ounces = 5/11 × 88
= 5 × 8
= 40 ounces.
