A clerk’s weekly salary of $320 is increased to $360. What is the percent increase?

Answer 1

`12.5%`

Explanation:

so first take out the amount of salary increased so it will be
`360-320=40`
after take out the percentage of the increased amount which was `$40` and the original amount which was `$320`
so `40/320 *100`
percentage increase `12.5%`
