Three companies sell their apple juice in different-sized bottles. Jade is calculating the unit prices of each bottle and will consider the one with the lowest unit cost to be the best buy. Which action will cause Jade to identify the best buy?

Question

dividing the cost of each bottle by its size
expressing each of the prices in cents instead of dollars
finding each unit price per quart instead of per ounce
leaving each unit price as an unrounded decimal

Answer 1

To determine the best buy among the different bottles of apple juice, Jade should take the action of dividing the cost of each bottle by its size.

This method will allow her to calculate the unit price, which is the cost per unit of measurement (such as per ounce or per quart). By comparing these unit prices directly, Jade can identify which bottle offers the lowest price for the same amount of juice, thus determining the best buy.

The other actions, such as expressing prices in cents, finding unit price per quart instead of ounces, or leaving unit prices as unrounded decimals, could either complicate the comparison or not provide the necessary information to identify the best value accurately.
