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
