Question

a) $32 dollars
b) $64 dollars
c) $72 dollars
d) $96 dollars

Answer 1

9514 1404 393

Answer:

(c) $72

Explanation:

Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...

12 × 12 = 144

tiles will be needed to cover the area.

The cost of 144 tiles at $0.50 each is ...

(144)($0.50) = $72.00
