Question

Identify as an increase or decrease then find the percent of increase or decrease. original 80new90

Answer 1

If the new is greater than the original, then it is an increase

Since the new is 90

Since the original is 80

90 > 80

New > original

Then it is the increase

To find the percent of increase subtract them and divide it by the original, then multiply the answer by 100%

`\text{Increase =}(90-80)/(80)*100`

The increasing percent is 12.5%
