You can purchase a 14 fl oz bottle of window cleaner for $2.26 or a 18 fl oz bottle for $2.92. Which bottle of window cleaner is the better deal? What is the unit price of this bottle?

Answer 1

14 for 2.26

18 for 2.92

2.26/14 = .161428 per oz

2.92/18 = .16222... per oz

The 14 oz deal is slighter cheaper, per ounce
