Tony was asked to bring root beer for root beer floats to the end of year class party. He is only given so much money for this budget. He finds a 64 ounce bottle for $3.20. What is a unit rate price per ounce?

To find the unit rate price per ounce, divide the total cost of the bottle by the number of ounces in the bottle: $3.20 / 64 ounces = $0.05 per ounce. The unit rate price per ounce is $0.05.
