 SliceOPi Jan 07, 2005 You can also just buy, 20 Pigs=\$60 80 Chickens=\$40 ---------------------- 100 animals=\$100 Gizzer Jan 07, 2005 Usually this teaser requires that at least one of each animal is purchased. I_am_the_Omega Jan 07, 2005 However, that wasn't stated. I did it the same way you did, Slice. castanz Jan 07, 2005 Make it simple. I bought 10 cows. Gizzer Jan 07, 2005 Then you're 90 animals short, castanz! Shaman_Talons Jan 07, 2005 lol duh cant only buy ten cows verve640 Jan 07, 2005 Another possible answer is 80 chickens and 20 pigs. Araldite Jan 08, 2005 That's what the first comment said! Duh. i_am_sam007 Jan 23, 2005 Its easy if you want to think about it, but I didn\'t feel like it today. But it was a good teaser. CPlusPlusMan Feb 05, 2005 9 Cows, 3 Pigs, and 2 Chickens is also an acceptable answer. CPlusPlusMan Feb 05, 2005 Wait, no it's not. My mistake. I forgot about the "exactly 100 animals part" eminemfreak69 Feb 07, 2005 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! Pat3033 Jul 19, 2007 how do i make a teaser of my own? opqpop Sep 11, 2010 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.
