Do cross multiplication, we get

Divide by 2x on both sides, we get

Answer:
She earned $959.2 last week.
Step-by-step explanation:
This question can be solved using a rule of three.
Base:
$500.
On commissions:
She earns 8.2% on commissions.
She sold $5,600, which is 100% = 1. How much is 8.2% = 0.082?
x - 0.082
5600 - 1
x = 5600*0.082 = 459.2.
She earns $459.2 on commissions.
Total:
500 + 459.2 = $959.2
She earned $959.2 last week.
