Final answer:
To determine which drink is the best value for your party, compare the prices per liter of each drink. The soda is the best value as it costs $0.49 per liter.
Step-by-step explanation:
To determine which drink is the best value for your party, we need to compare the prices and quantities of the drinks. A gallon of milk costs $2.99, a two-liter bottle of soda costs $0.99, and a 64-ounce bottle of apple juice costs $1.99.
First, let's convert the gallon of milk to liters. Since 1 gallon is approximately 3.785 liters, the cost of a gallon of milk per liter is $2.99 / 3.785 = $0.79 per liter.
Next, let's compare the prices per liter for the soda and apple juice. The cost of the two-liter bottle of soda is $0.99, so the price per liter is $0.99 / 2 = $0.49 per liter. The cost of the 64-ounce bottle of apple juice is $1.99, which is approximately 1.892 liters. So, the price per liter for the apple juice is $1.99 / 1.892 = $1.05 per liter.
Based on the prices per liter, the soda is the best value for your party as it costs only $0.49 per liter. The milk is slightly more expensive at $0.79 per liter, and the apple juice is the most expensive at $1.05 per liter.
