A rectangular floor that measures 24 meters by 64 meters is to be covered with carpet squares that each measure 8 meters by 8 meters. If the carpet squares cost $24 apiece, what is the total cost for the number of carpet squares needed to cover the floor?
Options:	A) $200	B) $576	C) $480	D) $960	E) $1,920
The width of the rectangular floor(24 m) is a multiple of one side of the square(8 m), and the length of the floor(64 m) is also a multiple of the side of the square. So the number of carpets to cover the floor is (24/8)*(64/8)=

24.   The total cost is 24*24=

<output>576</output>
$576.   The answer is, therefore, $576.
