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) She should work hours to make $130.

Answer 1

To find out how many hours Christiana needs to work, we need to determine how much money she needs to make after considering the $18 tip from hosting the birthday party.

1. First, subtract the tip from the total amount she needs to make for her car insurance: \[ 130 - 18 = 112 \] So, she needs to make $112 from her hourly wage.

2. Next, since she earns $14 per hour, we can calculate how many hours she needs to work to earn $112: \[ \text{Hours} = \frac{\text{Amount needed}}{\text{Hourly wage}} = \frac{112}{14} = 8 \]

Christiana should work 8 hours to make the remaining amount needed for her car insurance.
