Christina wants to compute the cost of tiling the floor in her bathroom. The floor measures 7 feet 6 inches by 8 feet 10 inches. Each tile covers 1 square foot. A box of 45 tiles costs $35.95.

How many boxes must she buy to cover the floor?

A. 1 box

B. 2 boxes

C. 3 boxes

D. 4 boxes

Respuesta :

Answer:

B. 2 boxes.

Step-by-step explanation:

Area of the floor = 7 1/2 *  8 5/6

= 15/2 * 53/6

=  265/4 feet^2.

Now we divide this are by 1 square foot  giving a total of 265/4

= 66.25 tiles

so she needs 2 * 45 tiles boxes (answer).
