Given the expression:
2.5x
Let's determine the situation which best represents the expression.
Let's start from the first statement:
• A. The total amount of change received to pay for an item that cost $2.50:
The best representation for this is: C = A - 2.50
Where A is the amount paid, C is the amount of change.
• B. The area of a rectangle with side lengths 2.5 and x:
The best representation for this situation is:
2.5x
• C. The total cost of an item that is 2.50 more than x dollars:
T = 2.50 + x
• D. The total square footage of a yard when 2.50 yards is divided into equal parts:
This expression cannot be represented by 2.5x
Therefore, the situation which can be represented by the expression 2.5 is:
The area of a rectangle with side lengths 2.5 and x
ANSWER:
B. The area of a rectangle with side lengths 2.5 and x
