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.

(christina is buying 2 boxes)

what is the cost of the tile needed for this project?

i got an answer of $71.9. is that correct?

Two boxes will cost The cost of one tile is approximately

Step-by-step explanation:

Note that 1 ft = 12 in, then

The area of the floor is

Now

then

144 sq. in - 1 tile,

9540 sq. in - x tiles.

Mathematically,

tiles is needed to cover the floor (67 full tiles).

Each box of tiles contains 45 tiles, so Cristina has to buy 2 boxes. These two boxes will cost The cost of one tile is approximately

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

answer is : muchas/tipicas

have a nice day!
