To determine how many hours Christiana needs to work to make $130 for her car insurance after receiving an $18 tip, we can first subtract the tip from the total amount she needs to earn.
Total amount needed: $130
Tip received: $18
Amount she still needs to earn:
$130 - $18 = $112
Next, we know she earns $14 per hour. To find out how many hours she needs to work, we divide the amount she needs to earn by her hourly wage:
Hours needed to work:
$112 รท $14 = 8
Therefore, Christiana should work **8 hours** to make $130 after receiving the tip.
Total amount needed: $130
