Marty saves 12% of his annual salary for a fund. this year, his salary was $3,000 more than last year. and he saved $3,600. what was marty's salary last year?

$27,000

Step-by-step explanation:

In order to calculate what his salary is this year, you need to divide $3,600 / 12% since $3,600 equals 12%. $3,600 / .12 = $30,000. If his salary is $30,000 it was 3,000 less last year, or $27,000.

a² + b²= c²

24² + 7² = c²

c= 25
