Question

Select the correct answer. You’re laying a new kitchen floor with square tiles that are one yard by one yard. Your rectangular kitchen is 24 feet by 33 feet, and each tile costs $54. You determine that the tiles will cost you $3,960. If you made a mistake in your pricing estimate, what most likely occurred?

A. You determined the number of tiles was 19 instead of 88.
B. You multiplied the number of tiles by $45 instead of $54.
C. You calculated the dimensions of your kitchen to be 3 yards by 4 yards instead of 8 yards by 11 yards.
D. No mistake was made.

Answer 1

The mistake that most likely occurred is multiplying the number of tiles by the wrong price.

Step-by-step explanation:

The mistake that most likely occurred is option B. You multiplied the number of tiles by $45 instead of $54.

To determine the number of tiles needed, you need to divide the area of the rectangular kitchen by the area of one tile. The area of the kitchen is 24 feet by 33 feet, which is a total of 24 x 33 = 792 square feet.

Since each tile is one yard by one yard, which is equivalent to 3 feet by 3 feet, the area of one tile is 3 x 3 = 9 square feet. To determine the number of tiles needed, divide the area of the kitchen by the area of one tile: 792 / 9 = 88 tiles.

Therefore, the correct answer is option B. You multiplied the number of tiles by $45 instead of $54.
