Jun 2, 2016

438.5%

#### Explanation:

A percentage change can be calculated using the following:

"amount of change"/"original amount" xx 100%

It is possible to have changes of more than 100%. For example, if an amount doubles, the change is 100%

In this case the amount changed from 13 to 70, an increase of 57.

57/13 xx 100% = 438.5%
