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?

  • Math -

    c = 3p, so adding up all the feet, we have

    2(3p)+4p = 2400
    10p = 2400
    so, there are 240 pigs

    c-p = 3p-p = 2p, so there are 480 more chickens than pigs.
