3.) Which is the better buy? $3.40 for a 12 ounce bag of chips or $.75 for a 3 ounce bag of chips?

it would be better to buy the 3 ounces because it’s cheaper. If you multiply .75 times 4 it would come out to 3.00 saving you 40 cents. .75 if the cost of a 3 ounce bag and 4 is how many times 3 goes into 12.

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
