If you break a twenty dollar bill into three five-dollar bills and three one-dollar bills, how many quarters do you need for change?

1. 3

2. 4

3. 6

4. 8

The correct answer is: 8

To determine how many quarters are needed for change after breaking a twenty dollar bill into three five-dollar bills and three one-dollar bills, we first need to calculate the total amount in bills. Starting with the total twenty dollar bill: - Three five-dollar bills total $15. - Three one-dollar bills total $3. Now, add those amounts together: - $15 (from the five-dollar bills) + $3 (from the one-dollar bills) = $18. The remaining amount from the twenty dollar bill when you subtract the total of the bills you have is: - $20 - $18 = $2. Next, we convert the remaining $2 into quarters. Knowing that one quarter is worth $0.25, we can find out how many quarters make up $2 by using the following steps: 1. Calculate how many quarters are in one dollar: - 1 dollar = 4 quarters. 2. Therefore, to find out how many quarters are in $2: - $2 = 2 x 4 quarters = 8 quarters. Thus, you will need 8 quarters to make up the remaining $2 after breaking the twenty dollar bill into smaller denominations. This clearly shows that the correct answer aligning with this
