each tile covers 4\frac{2}{3} 4 2 3 square feet ???

What is this? Is it 4 2/3 ft

^{2}per tile?14 ft 8 inches:

8 inches = 8/12 of a foot = 2/3 of a foot

So length is 14 2/3 ft

5 ft 6 inches = 5 1/2 ft

Floor area: (14 2/3)(5 1/2) = (44/3)(11/2) = 22(11)/3 = 242/3 ft

^{2 }of floor areaDivide the total floor area by the area covered by each tile to get the number

of tiles needed. If there is any fraction, round up to next whole number.

Multiply that number by the cost per tile.

If the area per tile is 4 2/3 ft

^{2}then:(242/3)/(4 2/3) = (242/3)/(14/3) = (242/3)(3/14) = 242/14 = 17.3 tiles.

Rounded up we need 18 tiles.

18(5) = $90
