8 / 0.04 = 200. We can do the equation in reverse to verify that 200 * .04 = 8. Also, 4/100 = 4%, so we could reason out that with 200 markers, the X/2 is the percentage, and 8/2=4. This isn't actually the correct math, though, and only works in this specific instance.

The volumes are the same.
The floor area to be tiled is 8 feet by 15 feet, which equals 120 square feet. Since each box covers 16 square feet, you will need 120/16 = 7.5 boxes of tiles. Since you can't buy half a box, round up to 8 boxes for 128 square feet, which will cost 8 * $48 = $384.
