The price of a cup of coffee was $2.15 yesterday. Today, the price rose $2.30. Find the percentage increase round your answer to the nearest tenth of a percent.

7%

Step-by-step explanation:

First, you find the difference between $2.30 and $2.15 to get the amount of change between the two numbers. We get $0.15, so we know that the change was 15 cents more. Next, we find the percent that 25 cents is to $2.15. You get 0.06976... and we can round it to the nearest tenth, which is 0.06. Then you convert that to a percent and you get 7% :)
