Question

A bakery uses 70% of its milk in one week. They now have 36 quarts of milk left. Find the number of quarts the bakery had at the beginning of the week.

Answer 1

120

Explanation:

At the beginning of the week, the bakery had x quarts

They use 70% of it, meaning that they are left with 30%

30% = 30/100 = 0,3 (when you calculate with %, you always need to calculate with %/100)

now you know that you have 30% (0,3) left and those 30% are 36 quarts

x*0,3=36

(this means: 30% of the number of quarts at the beginning)

x=36/0,3

x=120

hope i could help:)

Answer 2

The bakery starts a week with 100% quarts of milk.

In the course of the week they use 70%, meaning the remainder is 30% quarts of milk.

Therefore, the remaining quarts are equivalent to 30%

thus, 36 = 30% to get 100% ;

(36/30) ×100 = 120

Therefore, the bakery started the week with 120 quarts of milk
