1 answer

To determine how many hours Christiana needs to work to make $130 for her car insurance, we first need to account for the $18 tip she will receive.

  1. Calculate the amount she needs to earn after including the tip: \[ 130 - 18 = 112 \] So she needs to earn $112 from her hourly wage.

  2. Next, calculate how many hours she needs to work at her hourly rate of $14 to earn $112: \[ \text{Hours} = \frac{112}{14} = 8 \]

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