At store 1 I can buy 36oz of baby formula for 26.62 and at store 2 I can buy 28oz of baby formula for 22.42.Which one is a better buy and by how much?

Respuesta :

ur looking for the unit rate here....ur looking for dollars per oz....dollars/oz

store 1 : dollars / oz.....26.62 / 36 = 0.739 rounds to 0.74 per oz
store 2 : dollars / oz.....22.42 / 28 = 0.80 per oz

so the better buy, the cheapest one is : store 1, 26.62 for 36 oz <==
