To find out how many hours Christiana needs to work, we first need to account for the tip she will receive for hosting the birthday party.
1. **Calculate the total amount needed after the tip:**
Christiana needs to make $130 for her car insurance, and she will receive an $18 tip.
\[
\text{Amount still needed} = 130 - 18 = 112
\]
2. **Calculate the number of hours she needs to work:**
Christiana earns $14 per hour. Now we need to find out how many hours she needs to work to make the remaining $112.
\[
\text{Hours needed} = \frac{\text{Amount still needed}}{\text{Hourly wage}} = \frac{112}{14}
\]
\[
\text{Hours needed} = 8
\]
So, Christiana should work **8 hours** to make the $130 needed for her car insurance.
