Question

find the best buy based on price per unit. different brand of beans: 16 oz can at $1.07, 20 oz can at $1.20 or 35 oz can at $1.99

Answer 1

You want to find the base unit, which is price per oz. For the first can: 

 

$1.07/16 oz= .066 or 7 cents per oz

 

For the second can: 

 

$1.20/ 20 oz= .06 or 6 cents per oz

 

For the third can: 

 

$1.99/35 oz= .056 or 5.5 cents per oz

 

The can with the least price per oz is your best buy, so your answer is the third can.
