Your friend earns $10.50 per hour. This is 125% of her hourly wage last year. How much did your friend earn per hour last year?

We have the equation: \(1.25x=10.50\), so \(x=\boxed{8.4}\) dollars/

As a ratio:

 

$10.50 / 125 %  =   $x /100%

10.5 (100)/125 = $ x = $ 8.40/hr

You're right. I forgot the 0 at the end.

You were right too.....   $ 8.4/hr    is the same as $8.40/hr
