Final answer:
The student is dealing with a subtraction problem in which they've spent $2.75 out of $5.00, so they'll get back $2.25 in change.
Step-by-step explanation:
The subject of this question is Mathematics and it belongs to the Middle School grade level. This problem deals with the basic concept of subtracting to find the change. The question discusses a student purchasing a lunch and an extra beverage worth a total of $2.75, and decides to pay with a $5.00 bill.
To find out how much change will the student receive, we need to subtract the amount spent from the amount the student gave, i.e., $5.00 - $2.75 = $2.25. So, the student will receive $2.25 as change after the purchase.
