Okay so... .85/330 and 1.29/500 (Brand A) .0025757575757... and (Brand B) .00258 So it's Brand A (as shown above). ========================================================== Same way to solve... 3.75/75 (Brand A) and 5.90/125 (Brand B) .05 and .0472 So Brand B is the cheapest (Again with explanation above).
