If Gabrielle earned a weekly salary of $235.00 and earns 8% of the sales over $500, let's work to find what her weekly pay was if she had $6,250.00 in sales.

Now, our question tells that she get 8% commission of sales over $500.00.
If she made $6,250.00 in sales, then she would earn a "bonus" of 8% of her sales.

8% of $6,250 = $500.00

Her weekly salary is $235.00. Adding her "bonus" of the 8% of sales ($500.00), we would perform this equation:

$235.00 + $500.00 = $735.00 

Her total pay for that week is:
