Kama made fruit drinks for a party. She used a total of 168 ounces of bananas and blueberries. The recipe called for 3 ounces of bananas and 2 1/4 ounces of blueberries for each drink. How many ounces of blueberries did Kama use for the fruit drinks she made?

Answer: she used 72 ounces of blueberries.

Step-by-step explanation:

She used a total of 168 ounces of bananas and blueberries. This means that

x + y = 168

The recipe called for 3 ounces of bananas and 2 1/4 ounces of blueberries for each drink. This means that the ratio of ounces of bananas to blueberries used for each drink is 3 : 2.25

Total ratio = 3 + 2.25 = 5.25

Therefore, the number of ounces of blueberries did Kama use for the fruit drinks she made is

2.25/5.25 * 168 = 72 ounces.
