A customer pays a bill of $11.02 with $100. What is the correct change due using the least number of bills and coins?

• A. 5 $20 bills and 1 $5 bill
• B. 4 $20 bills, 1 $5 bill, 3 $1 bills, 3 quarters, 2 dimes, 3 pennies
• C. 1 $50 bill and 1 $38.98 in coins
• D. 10 $10 bills

Answer: (B)

The process of calculating the correct change due involves determining the difference between the amount paid and the total bill. Here, the customer pays $100 for a bill of $11.02. To find the change, subtract the bill from the payment:

$100.00 - $11.02 equals $88.98.

When providing change, the aim is to use the least number of bills and coins possible. The correct answer must consider both the values of bills and the combination of coins that would make up the total without duplicating higher denominations unnecessarily.

In option B, the change of $88.98 is broken down into a combination of different denominations, which can efficiently make up the total. It lists specific denominations that together amount to the total due, optimizing the use of coins and bills.

This means that using the breakdown in option B, you effectively use a mixture of higher denomination bills and various coins to achieve the correct total of $88.98 while minimizing the number of items given as change. This option demonstrates an understanding of cash handling principles, where both efficiency and accuracy are critical in customer transactions.
