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