Question

Last year40 people adopted a manatee through fias foundation. this year 30% more people adopted a manatee. how many more people adopted a manetee this year?

Answer 1

`12` more people

Explanation:

Find `30%` of `40`. That will automatically give you the answer.

`0.3*40=12`

Why it works:
Find `130%` of `40`.
`1.3*40=52`
Subtract `52` (which is `130%`) from `40` (which is `100%`).
`52-40=12`
`130%-100%=30%`
