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 find out how many hours Christiana needs to work, we first need to subtract the tip from the total amount she needs to make:

Total amount needed = $130
Tip received = $18

Amount she still needs to make = $130 - $18 = $112

Now, we can find out how many hours she needs to work at the rate of $14 per hour:

Hours needed = Amount needed / Hourly wage
Hours needed = $112 / $14 = 8 hours

So, Christiana should work 8 hours to make $130.
