Q:
Which is the better buy? 3 1/3 lb. of turkey for $10.50 OR 2 1/2 lb. of turkey for $6.25 ? PLEASE EXPLAIN HOW YOU GOT THE ANSWER! (MATHEMATICALLY)
Accepted Solution
A:
so we are looking for the price per lb....
price / lb : so be sure and put the price divided by the lbs
10.50 / (3 1/3) = 10.50 / (10/3) = 10.50 * 3/10 = 31.5/10 = 3.15 per lb
6.25 / (2 1/2) = 6.25 / (5/2) = 6.25 * 2/5 = 12.5/5 = 2.50 per lb
so the better deal is the 2 1/2 lb turkey <==
** keep in mind, when dividing fractions, flip what u r dividing by, then multiply
