Question

You can buy 3 apples at the quick market for $1.11. You can buy 5 of the same apples at the stop and save for $1.10. Which place is the better buy?

Answer 1

The better buy is the one that gets you more apples per dollar.

 

Quick market:  (3 apples)/($1.11) ≅ 2.7 apples/dollar

Stop and save:  (5 apples)/($1.10) ≅ 4.5 apples/dollar

 

The stop and save gets you more apples per dollar, and therefore is a better buy.
