Question

in wildlife park, there were 18 gray wolves. after three years, there were 27 gray wolves. what is the percent gain?​

Answer 1

50%

Explanation:

The percent gain is calculated as

`(gain)/(original)` × 100%

gain = 27 - 18 = 9 , then

percent gain =
`(9)/(18)` × 100% =
`(1)/(2)` × 100% = 50%
