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.
