You don't need to figure out the price per pound, because your answer options are all in ounces.
So this isn't grade 8 math, its more like grade 5.
Divide the price paid (4.12) by the number of ounces (32) to get the price for one ounce. Very simple.

B .13 per ounce because you take $4.12 and divide by 32 and it equals .13

Well first lets find the number of ounces in a pound. Thats 16 ounces in 1 pound.
Divide 32 ounces by 16 to find the wieght in pounds. Thats 2 pounds.
Then divide $4.12 by 2 to get the unit price per pound....$2.12
Divide by 16 to get the ounces...appox. $0.13 per ounce.

If you have 32 oz, and you want to find out how much one oz costs, just divide $4.12 by 32
$4.12/32 = .12875 or about .13

There are 16 0z in a pound. 32 oz is 2 pounds
1 pound is $4.12/2= $2.06
$2.06/16oz = 12.9 or $0.13/oz
b is the answer
