Question

Diet soda contains 90% less calories than regular soda. If a can of regular soda contains 112 calories, how many calories does a can of diet soda contain?

Answer 1

11.2 calories

Explanation:

Simply figure out the fewer calories in diet soda:

`112 * 90% or 112 * 0.9 = 100.8`

then subtract that amount from your regular soda to solve for diet soda:

`112-100.8 = 11.2`

So diet soda has 11.2 calories.
