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

A. Because Belle worked for 35hrs and she earns $12 per hour, which makes $420. Then Belle sold 2550 in cosmetics and 5% in decimals equals 0.05. Multiply 2550 by 0.05 and you get $127.50, that is the 5% commission for the 2550 Belle sold. Lastly add the $420 and $127.50 and you get $547.50 which is answer A.
