Question

Lucy bought 4 pairs of pants for $21.79 each. She paid the cashier using as few $20 bills as necessary. How much change did she receive?

Answer 1

The amount of change Lucy receives if she paid with few $20 bills is $12.84

How to find amount of change to receive

• 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
