Work out the percentage increase from 30 to 420.

First, we need to work out the difference (increase) between our two numbers:420 - 30 = 390
Second, we divide the difference by the original starting number:390 / 30 = 13
Lastly, we multiply this number by 100 to get the percentage increase:13 * 100 = 1300%
