3) Mr. Kelly, Mr. Brust and Mr. Sullivan all met by one common interest, THE BOBSLED! In fact they were pretty darn
good. In fact they were just one-thousandth of second from qualifying for the medals at the 1998 Nagano, Japan Winter
Olympics. While bobsledding they had to maintain a balance in terms of weight. The weight of the bobsled combined
with the weight of the three men couldn't be over 1200 pounds.

a) Make an inequality where x represents the weight of the bobsled and y represents the weight of the three men.

b) If the bobsled weighed 480 pounds what are all the possible weights of the three men combined?

c) Could the bobsled weigh 520 pounds and the men weigh 685 pounds? Why or why not?
