Question

Ana has 20 stickers. After 1 year she has 150 stickers. What percent increase in stickers?

Answer 1

650% increase

Explanation:

150/20 = 7.5

7.5 - 1 = 6.5

6.5 × 100 = 650%

Let's make sure this is correct.

650/100 = 6.5

6.5 + 1 = 7.5 The extra 1 represents the increase!

20 × 7.5 = 150

I hope this helps!! ^-^
