A rectangular floor that measures 8 meters by 10 meters is to be covered with carpet squares that each measure 2 meters by 2 meters. If the carpet squares cost $10 apiece, what is the total cost for the number of carpet squares needed to cover the floor?  Select
A) $200 B) $240 C) $480 D) $960 E) $1,920
The width of the rectangular floor(8 m) is a multiple of one side of the square(2 m), and the length of the floor(10 m) is also a multiple of the side of the square. So the number of carpets to cover the floor is (8/2)*(10/2)= 
<gadget id="calculator">(8/2)*(10/2)</gadget>
<output>20</output>
20.   The total cost is 20*10= 
<gadget id="calculator">20*10</gadget>
<output>200</output>
$200.   The answer is, therefore, $200.
