Counting money involves adding and subtracting the values of coins and bills. It is an important skill for everyday life and essential for understanding the concept of currency.
In the United States, common coins include pennies (1 cent), nickels (5 cents), dimes (10 cents), and quarters (25 cents). Common bills include $1, $5, $10, $20, $50, and $100.
To count a collection of coins, add the values of each coin together. For example, if you have 3 quarters, 2 dimes, and 4 pennies, you would calculate: (3 * 25) + (2 * 10) + (4 * 1) = 75 + 20 + 4 = 99 cents.
To count bills, simply add their values together. For example, if you have 2 $5 bills, 3 $10 bills, and 1 $20 bill, you would calculate: (2 * 5) + (3 * 10) + (1 * 20) = 10 + 30 + 20 = $60.
1. Count the following coins: 4 quarters, 3 dimes, 5 nickels, and 6 pennies.
Answer: (4 * 25) + (3 * 10) + (5 * 5) + (6 * 1) = 100 + 30 + 25 + 6 = 161 cents.
2. Count the following bills: 3 $1 bills, 2 $5 bills, and 4 $10 bills.
Answer: (3 * 1) + (2 * 5) + (4 * 10) = 3 + 10 + 40 = $53.
