Question

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

Answer 1

Answer:

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.

2212 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
