Christiana makes $14 per hour working at the roller-skating rink. She needs to make $130 to pay her car insurance. How many hours should she work if she receives an $18 tip for hosting a birthday party that day?(1 point)

Question

She should work ___ hours to make $130.

Answer 1

To determine how many hours Christiana needs to work to make $130 for her car insurance after receiving an $18 tip, we can first subtract the tip from the total amount she needs to earn.

Total amount needed: $130
Tip received: $18

Amount she still needs to earn:
$130 - $18 = $112

Next, we know she earns $14 per hour. To find out how many hours she needs to work, we divide the amount she needs to earn by her hourly wage:

Hours needed to work:
$112 ÷ $14 = 8

Therefore, Christiana should work 8 hours to make $130 after receiving the tip.
