The amount of change Lucy receives if she paid with few $20 bills is $12.84
<h3>How to find amount of change to receive</h3>
- Cost of each pair of pants = $21.79
- Number of pairs of pants = 4
Total cost of pants = $21.79 × 4
= $87.16
- Amount paid to the cashier = few $20 bills
If the total cost of the pants exceeds $80, then she paid with 5 $20 bills
5 $20 bills = $100
Her change = $100 - $87.16
= $12.84
