Answer:
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% :)
