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
