To solve this problem, we need to match each amount of money with the correct group of coins. We want to use the
least number of coins possible for each amount. This means we should always start with the biggest coin that fits into the amount and work our way down to smaller coins.
Here are the values of the US coins shown in the rows:
*
Quarter: 25¢
*
Dime: 10¢
*
Nickel: 5¢
*
Penny: 1¢
Let's break down each row step-by-step:
1. Amount: 15¢
* Can we use a Quarter (25¢)? No, it's too big.
* Can we use a Dime (10¢)? Yes. $15 - 10 = 5$ cents left.
* Can we use a Nickel (5¢) for the rest? Yes. $5 - 5 = 0$.
*
Coins needed: 1 Dime and 1 Nickel.
2. Amount: 9¢
* Can we use a Dime (10¢)? No, too big.
* Can we use a Nickel (5¢)? Yes. $9 - 5 = 4$ cents left.
* We need 4 more cents. We must use Pennies (1¢).
*
Coins needed: 1 Nickel and 4 Pennies.
3. Amount: 22¢
* Can we use a Quarter (25¢)? No, too big.
* Can we use a Dime (10¢)? Yes. Let's use two dimes because $10 + 10 = 20$. That leaves 2 cents ($22 - 20 = 2$).
* We need 2 more cents. Use Pennies.
*
Coins needed: 2 Dimes and 2 Pennies.
4. Amount: 45¢
* Can we use a Quarter (25¢)? Yes. $45 - 25 = 20$ cents left.
* Now we have 20 cents left. Can we use another Quarter? No.
* Can we use Dimes (10¢)? Yes. Two dimes make exactly 20 cents ($10 + 10 = 20$).
*
Coins needed: 1 Quarter and 2 Dimes.
5. Amount: 19¢
* Can we use a Quarter? No.
* Can we use a Dime (10¢)? Yes. $19 - 10 = 9$ cents left.
* For the remaining 9 cents, can we use another Dime? No.
* Can we use a Nickel (5¢)? Yes. $9 - 5 = 4$ cents left.
* For the last 4 cents, we use Pennies.
*
Coins needed: 1 Dime, 1 Nickel, and 4 Pennies.
6. Amount: 20¢
* Can we use a Quarter? No.
* Can we use Dimes (10¢)? Yes. Two dimes make exactly 20 cents.
*
Coins needed: 2 Dimes.
7. Amount: 13¢
* Can we use a Quarter? No.
* Can we use a Dime (10¢)? Yes. $13 - 10 = 3$ cents left.
* For the remaining 3 cents, we use Pennies.
*
Coins needed: 1 Dime and 3 Pennies.
8. Amount: 37¢
* Can we use a Quarter (25¢)? Yes. $37 - 25 = 12$ cents left.
* For the remaining 12 cents, can we use another Quarter? No.
* Can we use a Dime (10¢)? Yes. $12 - 10 = 2$ cents left.
* For the last 2 cents, we use Pennies.
*
Coins needed: 1 Quarter, 1 Dime, and 2 Pennies.
