if something was $.69 and it got marked up to $1.59 what is the percent of increase

Question

Pleaseeeee help I have no idea how to do This 

Answer 1

I believe the answer is 130.43%

$1.59-$.69 = $.9

.9/.69=1.3043 = 130.43%

Answer 2

The percent increase is the AMOUNT of the increase divided by the original price, then times 100.

 

First figure out the AMOUNT of the increase.  That's $1.59 - $.69 = $.90.

 

.90 / 1.59 = 0.566

 

So the percent increase is 0.566 x 100 = 56.6 %
