Belle sells cosmetics at a local store. She earns $12.00 for every hour she works she also earns 5% commission on all sales that she makes. Last week, Belle worked 35hrs and sold 2,550.00 in cosmetics. What is Belle’s total earnings for last week?
A. $547.50
B. $1,695.00
C. $420.00
D. $645.50

The correct answer is A $547.50

12•35= 420 which is how much she was paid for working 35 hours
next we need to find how much she makes from commission
to do this we need to multiply $2,550 by 5%
2550•.05= 127.50

to find her total earnings we need to add the two answers together
$420+$127.50 =$547.50
