A bakery uses 70% of its milk in one week. They now have 36 quarts of milk left. How many quarts did the bakery use during the week? The bakery used quarts of milk. Part C There are 4 quarts in a gallon. How many gallons of milk did the bakery use during the week?

Part 1)

Data:

70% milk used in a week

36 quarts of milk left

How many quarts used during the week?

Solution:

(Here we are supposed to find the milk USED, which is 70%, now we know that milk which is left is 36 quarts and it is obvious that the percentage of the milk left is 30% because 100% - 70% = 30%. )

You'll get your answer through the following equation:

(70% × 36 quarts) ÷ 30% = 84 quarts

Therefore, the bakery used 84 quarts of milk during the week.

Part 2)

Data:

1 gallon = 4 quarts

Solution:

(Here, we're simply asked to convert the quarts of milk used during the week into gallons.)

If 1 gallon is 4 quarts, then:

84 quarts ÷ 4 = 21 gallons

Therefore, the bakery used 21 gallons of milk during the week.
