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)

1 answer

To determine how many hours Christiana should work to make $130 for her car insurance after receiving an $18 tip, we can first calculate how much more money she needs after receiving the tip.

  1. Calculate the money she still needs after the tip: \[ 130 - 18 = 112 \] So, she needs $112 from her hourly wage.

  2. Now, we know she makes $14 per hour. To find out how many hours she needs to work to earn $112, we can set up the equation: \[ 14h = 112 \] where \( h \) is the number of hours she needs to work.

  3. Solve for \( h \): \[ h = \frac{112}{14} = 8 \]

Therefore, Christiana should work 8 hours.
