Question

The price of a notebook was 3.30 yesterday. Today, the price rose to 3.80 . Find the percentage increase. Round your answer to the nearest tenth of a percent. @Convert I need your help

Answer 1

Well the formula to find the percent increase is to divide the increase by the original number then multiply by 100:
3.80-3.50= 0.30
0.30 x 100 = 30% increase

Thanks :D

Answer 3

No problem :)

Answer 4

I'm suppose to round to the nearest tenths

Answer 5

Oh wait I did it wrong-

Answer 6

3.80-3.30 = 0.50
0.50/3.30 = 0.1515
0.1515 * 100 = 15.15% increase

Answer 7

15.15% rounds up to 15.2%

Okay! Thanks @Convert
