Which combination is equivalent to $125.00?

1. Nine $10 bills and five $5 bills

2. Five $20 bills and three $5 bills

3. Four $20 bills and eight $5 bills

4. Six $20 bills and one $5 bill

The correct answer is: Six $20 bills and one $5 bill

To determine which combination of bills equals $125.00, we need to calculate the total value of each option. For the option that you thought was correct, which is six $20 bills and one $5 bill, we calculate the total as follows: - Six $20 bills amount to \(6 \times 20 = 120\). - One $5 bill adds an additional \(5\). Adding these together: \[ 120 + 5 = 125 \] This confirms that six $20 bills and one $5 bill sums to $125.00. When solving similar questions, it can be helpful to break down the values of each combination of bills to see if they fulfill the required total. Understanding how to manipulate and combine different denominations accurately ensures you arrive at the correct total.
