Answer from: Quest

In order to find the price per bar, we divide the price by the amount of bars. for the first one: 15.37/10 = $1.54 per barthe second package: 15.35/12 = $1.28 per bar.the 10-pack costs $1.54 per bar and the 12-pack costs $1.28 per bar. the 12-pack has the better price per bar.now, let's look at the price per ounce. we do this in a similar way. we find the total amount of ounces in the package, and divide the price by the number of ounces.in the first package, we multiply 10*2.1=21. we have 21 ounces in the first package. now we divide 15.37/21. in the first package, we have 0.73 dollars per ounce.now, let's look at the second package. we start by multiplying 1.4*12=16.8. there are 16.8 ounces in the package. now, we divide 15.35/16.8=0.91. so, in the second package, we have 0.91 dollars per ounce.the cost per ounce of the 10-pack is $0.73 and the cost per ounce of the 12-pack is $0.91. the first package has the better price per ounce.the better explanation is the second one, because i prefer the lower price per ounce, i think that the 1st pack is the better buy.
