Question

Find the percent of increase for 4 to 7. round to the nearest tenth if necessary. also someone please explain how to do this.

Answer 1

75%

Explanation:

The percent increase is calculated as

percent increase =
`(increase)/(original number)` × 100%

increase = 7 - 4 = 3, thus

% increase =
`(3)/(4)` × 100% =
`(3(100))/(4)` = 75%
