Answer:
$18
Step-by-step explanation:
Given the following data;
Number of friends = 8
Total expense = $120
Tip = 20%
To find how much each friend would pay?
First of all, we would determine the amount of tip.
Tip = 20/100 * 120
Tip = 2400/100
Tip = $24
New balance = total expense + tip
New balance = 120 + 24
New balance = $144
Next, we find how much each friend would pay using the mathematical expression;
Each paid = 144/8
Each paid = $18
