First, let's calculate how much Christiana needs to make after her tip.
She wants to make $130 to pay her car insurance, and she is receiving an $18 tip:
\[
130 - 18 = 112
\]
This means she needs to earn $112 from her hourly wage.
Now, since she makes $14 per hour, we can determine how many hours she needs to work by dividing the amount she needs to earn by her hourly wage:
\[
\frac{112}{14} = 8
\]
Therefore, Christiana should work **8 hours** to make $130.
