Final answer:
To find the total price of the carpeting for Walter's living room, multiply the area of the room (450 square feet) by the cost per square foot ($3.25), which results in a total price of $1462.50.
Step-by-step explanation:
Walter wants to buy carpeting for his living room, which measures 25 x 18 feet. To determine the total price, first, calculate the area of the room and then multiply by the cost per square foot. The area is found by multiplying the length by the width.
Area = Length × Width = 25 feet × 18 feet = 450 square feet.
Next, multiply the area by the cost per square foot of the standard grade carpeting.
Total Price = Area × Cost per square foot = 450 square feet × $3.25 per square foot = $1462.50.
Therefore, the total price of the carpeting for this room is $1462.50.
