Question

I am thirsty but also thrifty so I want a drink that will quench my thirst and cost the least. Which of the following will quench my thirst and cost the least? Write the unit rate for each.

-A 12oz Pepsi $1.08
-A 20oz coke for $1.20
-A 24oz mountain dew for $1.68

Answer 1

You need to find the cost per ounce.
Just divide the price by the amount of ounces.
Once you do this, you get .09, 0.06, and 0.07.
The coke costs the least per ounce. It’s the one.
