There are three times as many chickens than pigs on a farm. All the chickens and pigs have 2400 feet all together. How many more chickens than pigsare there?

c = 3p, so adding up all the feet, we have
2(3p)+4p = 2400
10p = 2400
so, there are 240 pigs
cp = 3pp = 2p, so there are 480 more chickens than pigs.
