To determine which is the best buy, we need to first find the unit price of each
8 oz $2.40
Unit price
$2.40/8 = $0.3
1 oz = $0.3
24 oz $6.48
Unit price
$6.48/24 =$0.27
1 oz = $0.27
64 oz $14.08
Unit price
$14.08/64 =$0.22
From the above the best best buy is the one with the lowest price which is $0.22
The best buy is;
64 oz $14.08
and the unit rate is $0.22 per oz
