Arthur is putting a tile floor in this room. The tiles are 1 foot on each side. Half of the tile will be dark brown tiles that cost $.50 each the other half will be light brown tiles that are on sale for $.49 each how much will the tiles for this floor cost

The size of the floor is not given. From online sources, it's 17ft x 8ft.

$65.34

Step-by-step explanation:

Area of the entire floor = 17 × 8 = 136 ft²

Now we are told that half of the entire floor tiles will be dark brown tiles while the other half will be light brown tiles.

Thus;

Area of dark brown tiles = 136/2 = 66 ft²

Area of light brown tiles = 136/2 = 66 ft²

Now, we are told that a piece of both colour of the tiles are 1 ft on each side, which means that:

area of 1 piece of tile = 1 × 1 = 1ft²

Thus,

Number of dark brown tiles = 66/1 = 66 tiles

Number of light brown tiles = 66/1 = 66 tiles

Now, cost of each dark brown tile is given as $0.50

Thus,total cost of dark brown tiles = 66 × 0.5 = $33

Cost of each light brown tile is given as $0.49

Thus,total cost of light brown tiles = 66 × 0.49 = $32.34

Thus, total cost of all floor tiles = $33 + $32.34 = $65.34

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
