After purchasing two items for $11.23 and $8.32 with a $20 bill and a $5 bill, how much money does Sarah have left?

To determine how much money Sarah has left after her purchases, we first need to calculate the total amount she spent as well as the total amount she had initially.

Sarah purchased two items, costing $11.23 and $8.32. Adding these two amounts gives:

$11.23 + $8.32 = $19.55

Next, we find out how much money Sarah started with. She used a $20 bill and a $5 bill:

$20 + $5 = $25

Now, to find out how much she has left after her purchases, subtract the total cost of the items from the initial amount:

$25 - $19.55 = $5.45

This means Sarah has $5.45 remaining after her purchases. The calculation clearly shows how the subtraction of her total spending from her initial funds leads to the answer of $5.45, confirming that the correct answer is indeed appropriate for the problem scenario given.
