You do not have enough money to pay your sister back and the amount left is $29
<h3>A. Do you have enough money to pay your sister back? </h3>
The given parameters are:
Amount borrowed = $130
Earnings = $12 per hour for 4 hours
Earnings = $12 per hour for 6 hours
Tip = $5
The total earnings is
Total = 12 * 4 + 12 * 4 + 5
Evaluate
Total = $101
101 is less than 130
Hence, you do not have enough money to pay your sister back
<h3>How much money left</h3>
The amount left is calculated as:
Amount left = $130 - $101
Evaluate
Amount left = $29
Hence, the amount left is $29
