At one store, a 2-liter bottle of soda costs $2.12. At another store, a 3-liter bottle costs $3.15. Which bottle is a better deal? Write a division equation for each 2-liter bottle, and then decide which is the better deal. (To make this easier the first store is called "Dollar Store" and the 2nd store is called "Super Dollar". Don't judge the names I couldn't think of anything else.)
