Which is the better buy: 7 pounds for $8.47 or 9 pounds for $11.07?

First we find the average cost per pound... (7n)/7 = ($8.47)/7 = $1.21 per pound (9n)/9 = ($11.07)/9 = $1.23 per pound
$1.21 is the cheapest price per pound, so 7 pounds for $8.47 is a better buy
Answer = 7 pounds for $8.47 is the best buy
