To find out how much change Katy receives, we first subtract the cost of the book from the amount she paid:
$5.00 – $3.81 = $1.19
Now, we need to give her $1.19 in the least number of coins and bills possible. Here’s the breakdown:
1. One-dollar bills: She can receive 1 one-dollar bill.
– Amount left: $1.19 – $1.00 = $0.19
2. Quarters: The next highest denomination is the quarter (25 cents). Since $0.19 is less than 25 cents, she receives 0 quarters.
3. Dimes: Dimes are worth 10 cents. She can receive 1 dime:
– Amount left: $0.19 – $0.10 = $0.09
4. Nickels: Nickels are worth 5 cents. She can receive 1 nickel:
– Amount left: $0.09 – $0.05 = $0.04
5. Pennies: Lastly, she can receive 4 pennies:
– Amount left: $0.04 – $0.04 = $0.00
So, Katy will receive:
– One-dollar bills: 1
– Quarters: 0
– Dimes: 1
– Nickels: 1
