Question

The price of a notebook was $3.40 yesterday. Today, the price rose to $3.90 . Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

Hello

So we can divide the old value by the new to get the percentage

3.40/3.90 = 0.87

Now we subtract this by 100%

1 - 0.872 = 0.132

The price when up 13.2%

Hope this helps!
