The cost of a jacket increased from $85.00 to $94.35. What is the percentage increase of the cost of the jacket?

Serggg [28]

It's an 11% increase. To find this, you have to subtract 85 from 94.35 and then you divide that difference by the original amount. In this case it's 85. After that, you get .11. Then you just turn it into a percent.
