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 his budget. He finds a 64 ounce bottle for $3.20. What is the unit unit rate price per ounce?

To find the unit rate price per ounce, divide the total cost of the 64 ounce bottle of root beer by the number of ounces: $3.20 / 64 = $0.05/ounce. Answer: \boxed{5}.

To find the unit rate price per ounce, you need to divide the total cost by the number of ounces.

Total cost: $3.20
Number of ounces: 64

So, the unit rate price per ounce can be calculated as:

Unit rate price per ounce = Total cost / Number of ounces
= $3.20 / 64
= $0.05

Therefore, the unit rate price per ounce is $0.05.

To find the unit rate price per ounce, we need to divide the total cost ($3.20) by the number of ounces in the bottle (64).

Price per ounce = Total cost / Number of ounces

In this case, the total cost is $3.20 and the number of ounces is 64. Let's plug these values into the formula:

Price per ounce = $3.20 / 64

Now, we can simplify the expression by dividing $3.20 by 64:

Price per ounce = $0.05

Therefore, the unit rate price per ounce is $0.05.
