Question

What is the percent of change from 30 to 51?

Answer 1

Answer: 170%

Explanation:
1) find the difference

51 - 30 = 21

2) divide starting number from result

((51 - 30)/30) = .7

3) multiply it by 100 to change into percent

.7 * 100 = 70%

4) now just add another 100 percent to it cus it like increased ( if that makes sense )

170%
