"A rooster is worth five coins, a hen three coins, and 3 chicks one coin. With 100 coins we buy 100 of them. How many roosters, hens, and chicks can we buy?" Hint: Chicks have to be bought in multiples of 3. There are 4 different possibilities. I won't post the answer until someone answers since last time it didn't work so well

Yup, that's probably the easiest one to come up with w/o doing actual math. P.S. This question's from my linear algebra class so we had to use matrices...

I would assume you'd need to buy one of at least all 3? Yeah? If so, how bout: 8 roosters - 40 coins 11 hens - 33 coins 27 chicks - 81 coins

Umm I refuse to take part in a gender discriminating thing why is a hen worth less? That's what I would write if I had to do this in school. Hehe

Wait..that didn't work out right. Duh! I had it all figured out, typed the wrong answer, then threw away my work. Let me write this out again.. I feel like a dumbass!!

If anything, it should be the other way around, since hens are not only food in themselves, but also lay eggs. Roosters just make a lot of noise!

OK, how about: 4 roosters - 20 coins 18 hens - 54 coins 78 chicks - 26 coins ------------------------ 78 26 18 54 +4 +20 ----------------------- 100 100

I took linear algebra but I can't remember a thing about it! Matrices have proven useless to me in the real world so my brain seems to have tossed out any knowledge of them I do remember liking that class though!

Yeah I think courses that we have to take simply allow our brains to be twisted before the real world!
