Original amount:30
end amount: 45

Answer 1

The percent increase is 50%

Explanation:

The question is

Find out the percent increase

we know that

The original amount represent the 100%

so

30 represent 100%

using proportion

Determine what percentage represent the difference between the end amount and the original amount

so

`(30)/(100\%)=(45-30)/(x)\\\\x=100(15)/30\\\\x=50\%`

therefore

The percent increase is 50%
