You have a large container of olive oil. You have used 22 1/2 quarts of oil. Twenty - five percent of the oil remain. How many quarts of olive oil remain

7.5 quarts of olive oil remain.

Explanation:

Let

q = quarts of olive oil remain

25% of olive oil remains means that 75% has been used.

22 12 quarts = 22.5 quarts used

22.5.75 = q. 25

Multiply both sides by. 25 to isolate q.

22.5.75 (.25) = q. 25 (.25)

5.625.75 = q

7.5 = q
