Question 518175: if you have $100 and you have to buy 100 animals cows cost $10 pigs cost $5 and chickens cost $0.50
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! I guess the question is:
How many of each do you buy?
-------
I can't buy 10 cows, since that uses up the $100
If I buy 9 cows, I can buy 1 pig and 10 chickens
That's only 20 animals. I need a lot more chickens.
------------
7 cows = $70
2 pigs = $10
40 chickens = $20
(49 animals)
-----------
6 cows = $60
1 pig = $5
70 chickens = $35
(77 animals)
-----------
5 cows = $50
1 pig = 5$
90 chickens = $45
(96 animals)
-----------
4 cows = $40
1 pig = $5
110 chickens = $55
( too many chickens)
-----------
4 cows = $40
2 pigs = $10
100 chickens = $50
(still too many chickens)
-----------
4 cows = $40
3 pigs = $15
90 chickens = $45
-----------
4 cows doesn't work, so
3 cows = $30
4 pigs = $20
100 chickens = $50
----------
3 cows = $30
5 pigs = $25
90 chickens = $45
----------
1 cow = $10
9 pigs = $45
90 chickens = $45
That's it 100 animals
$100
