To determine how many hours Christiana needs to work, we first need to calculate how much she still needs to make after her tip.
1. **Total needed for car insurance:** $130
2. **Amount received from the tip:** $18
Now, we subtract the tip from the total she needs:
\[
130 - 18 = 112
\]
So, she needs to make $112 from her hourly wage.
Next, we find out how many hours she needs to work at her hourly rate of $14:
\[
\text{Hours} = \frac{\text{Amount needed}}{\text{Hourly rate}} = \frac{112}{14} = 8
\]
Therefore, Christiana should work **8 hours** to make the required amount for her car insurance.
