Sally has 2 chickens, 3 cows and 2 motorcycles. Doug has 6 monkeys, 12 pigs and 2 tractors. Amy has 1 car, 10 cows and 6 ducks. How many farm animals do Sally, Doug and Amy have in total?
Chickens, cows, ducks and pigs are commonly considered to be farm animals because they are commonly raised in farms and are grown for human consumption. Meanwhile, monkeys are not considered to be farm animals because they often grow up in the wild and are not often consumed by humans. Cars, motorcycles and tractors are not living things so they are not farm animals. Sally, Doug and Amy have 2 + 3 + 12 + 10 + 6 = 33 farm animals in total.
