Question

The percent increase of an item that jumped from $27 to $30 is approximately _____.

Answer 1

30-27 is how much
then take that number and divide it by 27
and find a percent that is close to that


30-27 = 3
3/27 = 1/9
1/9 is greater than 1/10(10%) but less than 1/8(12.5%)
so it is in between 10% and 12.5%, or
9*11% = 99% , 99% is almost 100%
