You go to a farm sale with exactly $100.00 to spend, and you have to buy exactly 100 animals.
Horses are $10.00 ea.
Hogs are $2.50 ea.
Chickens are .50 (cents) ea.
You must to buy some of each animal. Again, you must spend exactly $100.00 and must buy exactly 100 animals. How many of each do you buy? funtwohunt

4 horses = $40
6 hogs = $15
90 chickens = $45
100 & 100
Right?

No cows?

I wouldn't bother with the auction. At those prices the auction was over before my father was born.

You are right. How did you figure it out?

I get 4 horses, 6 hogs and 90 chickens. just found somewhere to start and worked the numbers a bit.

funtwohunt,
Had 2 equations with 3 unknows. That is not wokable with simple math, BUT you know the Number of horses must be between 1 and 9 so I just plugged in 9 ,8 ... at 4 horses it worked out.
2 equations with 2 unknowns is workable. I did not check to see if there was more than one solution?
One 3 x 5 card with some scribbles did it.
