A farmer who has four cows ready to go to market. He trades the cow for chicken at the rate of 20 chickens per cow. He trades the chickens for pig at a rate of 15 chickens per 2 pigs. On average, each pig weighs 140 lb. The pig he trades for corn, 3 bushels of corn per pound of pig. The corn is then traded for wheat at 1 bushel of wheat per 2 bushels of corn.   Wheat is premium, so he trades it for rye, 5 bushels of rye per bushel of wheat. He gives the rye to his friend, a baker, who makes 500 loaves of bread for each bushel.   The loaves of bread are taken to his pet store, and he can feed 3 birds per loaf of bread. The birds are used to feed snakes, and each snake eats an average of 9 birds before being sold for $32.00 each. How much money did the farmer make from the four cows?

Solution

He trades the cow for chicken at the rate of 20 chickens per cow. --- 4x20 chicken

He trades the chickens for pig at a rate of 15 chickens per 2 pigs

Pigs ----80(x 2/15) x 140 (each pig weighs 140 lb.)

wheat -----80(x 2/15) x 140 x1/3 x1/2

Rye -------------80(x 2/15) x 140 x1/3 x1/2 x 5

The loaves of bread are taken to his pet store, and he can feed 3 birds per loaf of bread.

loafs -----80(x 2/15) x 140 x1/3 x1/2 x 5 x 500 x4

each snake eats an average of 9 birds

snacks ----- $ 80(x 2/15) x 140 x1/3 x1/2 x 5 x 500 x4 x1/9 x 32

= $ 59733,33.3
