Answer 2

we know that

$
`18` represent the
`100`%

so

by proportion

`(18)/(45) =(100)/(x) \\ \\ 18*x=45*100\\ \\ x=(45*100)/(18)`

`x=250`%

so

$
`45` represent the
`250`%

Find the percent increase

`Percent\ increase =250-100=150`%

therefore

the answer is

The percent increase is equal to
`150`%
