100 animals 100 dollars riddle answer
Answer: 5 cows =$50, 1 pig =$3. 94 ducks =$47
Explanation: Answer : 5 cows =$50 1 pig =$3 94 ducks =$47 Explanation: let number of cows be x let the number of pigs be y then the number of chickens = 100-x-y 10x + 3y + .5(100-x-y) < 100 times 2 20x + 6y + 100 - x - y < 200 19x + 5y < 100 consider 19x + 5y = 100 But , what is the question? Do you want the different combinations you can buy? Do we want as close as possible to $100? Remember x and y have to be positive integers. so x has to be between 1 and 5 form a table with columns x, y, and 100-x-y, and cost 1 16 83 99.50 1 15 82 86.00 ... 5 1 94 100 x=5, y=1 is the only combination that will use all the money He should buy 5 cows, 1 pig and 94 chickens 5+1+94 = 100 $50 + $3 + $47 = $100
