Question

masons favorite brand of peanut butter is available in two sizes. the regular size is 16 oz and the price is 3.36. the family size is 40 oz and the price is 7.60. which size is the better buy

Answer 1

EXPLANATION

Let's see the facts:

Regular size= 16 oz

Price = 3.36

Family size = 40 oz

Price = 7.60

The better peanut to buy is the one who gives the best weight/price rate, so dividing the weight of each butter by their price give us:

Regular size rate = 16oz/$3.36 = 4.76 oz/$

Family size rate = 40oz/$7.60 = 5.26 oz/$

So, the family size is the best choice because it give us the most quantity of peanut butter by dollar.
