Which store sells each item for less?
al & al's farm - 1 gallon for $3.35 or old bessie milk $1.29 for a quart

So convert to quarts
1 gallon=4 quarts
4 quarts=3.35
therfor divide al and al's farm milk by 4 to get 1 quart
3.35/4=0.83
0.83 coparedto 1.29
0.83 is less so it is better deal

Al& AL's farm sels for less

There are 4 quarts in 1 gallon.
A gallon from Bessie costs
4 x 1.29 = $5.16 .

As I have been saying for years now ...
You'll always get the better deal from Al.

There would be 36.35 pounds
