For this question, you need to find the price per unit. The unit in this case is a note, so we are looking for the price of each individual note in the package. The way we find this is by taking the price divided by the number of notes So package one would come out to be (9/18) or .50 dollars per note. Package two would come out to be (12/16) or .75 dollars per not. Package three would be (4/10) or .40 dollars per note. Your answer would simply the one with the lowest price per note, and in this case would be package three
