Question

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 can first determine how much she needs to earn from her hourly wage after accounting for the tip.

1. Calculate the amount she still needs after receiving the tip:
\[
\text{Amount needed} = \text{Total needed} - \text{Tip}
\]
\[
\text{Amount needed} = 130 - 18 = 112
\]

2. Next, determine how many hours she needs to work to earn that remaining amount using her hourly wage:
\[
\text{Hours needed} = \frac{\text{Amount needed}}{\text{Hourly wage}}
\]
\[
\text{Hours needed} = \frac{112}{14} = 8
\]

Therefore, Christiana should work **8 hours** to make $130.
