You can also just buy,

20 Pigs=$60
80 Chickens=$40
----------------------
100 animals=$100

Usually this teaser requires that at least one of each animal is purchased.

However, that wasn't stated. I did it the same way you did, Slice.

Its easy if you want to think about it, but I didn\'t feel like it today. But it was a good teaser.

9 Cows, 3 Pigs, and 2 Chickens is also an acceptable answer.

Wait, no it's not. My mistake. I forgot about the "exactly 100 animals part"

OK this is my teaser, and it does say you have to buy at LEAST one of each so people really need to read it and think, i bet a lot of people couldnt figure it out or it took a long time. well idk i hope you all got it!

We know

10a + 3b + 1/2c = 100
a + b + c = 100

Multiply first equation by 2 and subtract the bottom equation to get

19a + 5b = 100.

You can quickly see a = 5 and b = 1 works. Then c = 94 and you're done.
