- Mary earns an hourly wilge of $13 plus a $90
SIZIF [17.4K]

Answer:

39 hours

Step-by-step explanation:

Mary earns an hourly wage of $13

plus a $90 bonus.

Subtracting the bonus we get;

$597 - $90 = $507

1 hour -> she gets $13

how many hours will she get $507

Cross multiplying gives;

\frac{507}{13}  * 1 = 39 hours
