Julio makes a mocktail every evening. He uses 1 tablespoon of lime juice and tops with 1 cup of sparkling water.  He can usually squeeze 2 tablespoons of lime juice per lime. After 30 days, if limes are 3 for $1.00, how much will he have spent on limes?

How many tablespoons of lime juice does Julio use? ** He uses 1 tablespoon of lime juice per drink so over 30 days that's 1*30 = <<1*30=30>>30 tablespoons of lime juice
How many limes will Julio need? ** He can get 2 tablespoons of lime juice per lime and he will use 30 tablespoons of lime juice so he will need 30/2 = 15 limes
How much will Julio spend on limes? ** The limes are 3 for $1.00 and he needs 15 limes so that's 15/3 = $5.00
