To find percentage increased, you want to take the amount of the change and divide it by the original amount.
00:13
So change over original.
00:15
So in choice a, we went from 80 to 90.
00:20
So we're going to calculate 10, which is going to be the amount of the change over 80.
00:27
And 10 divided by 80 is going to give you 0 .1 .1.
00:33
25 or 12 .5%.
00:37
B is 5 ,000 to 6 ,000.
00:42
So that's a thousand change over 5 ,000, the original amount.
00:49
1 ,000 divided by 5 ,000 is 0 .2, so that's a 20 % change.
00:56
Okay, so we want the highest.
00:58
We're going to cross off a because so far b is highest...
