Makalya wants to buy a carton of juice she could buy a 48 ounce container for 2.88$ or a 64 ounce container for 3.20.$

To figure out which carton of juice she should buy, divide the price by the number of ounces and see which one costs less per ounce.

2.88/48=0.06

3.20/64=0.05

The 64 ounce container costs less per ounce, so she should buy that one.
