Know the Answer?

Jonathon Stephens · Answer 1

The answer is c. 20% of 15 is 3. 15+3=18

Boyer · Answer 2

The correct answer is 20% because the formula is change/original. The change between 18 and 15 or the difference is 3. so it is 3/15 because 15 is the original number of books that she read. The answer is 20%
