A carton contains milk that is 2% fat, an amount that is 25% less fat than the amount contained in a carton of whole milk. What is the percentage of fat in whole milk?
Saying "25% less" is the same as saying "75% of".
2% = 0.02 and 75% = 0.75
Let x stand for the percentage of fat in the whole milk.
(0.75)(x) = 0.02
x = (0.02) / (0.75) = 0.02667
So, the amount of fat in the whole milk is 2.667%
Check Answer
(0.02667) • (0.25) = 0.00667
0.02667 – 0.00667 = 0.02
