math sucks, but i'm kinda good at it

Get this...I'm watching AI (this season pretty much sucks, by the way), and the phone rings.  It's my niece (the one I usually don't talk to, since the last time I talked to her, she was high as a kite), asking me a favor.  Oh no, what the hell does she want...money, a ride...?  Nope...help with a math question...WTF?  Proceeds to tell me she's at a friend's house, and friend needs help with an algebra problem.  Niece says she can't help, since she's a stupid dropout (her words, not mine), so she calls me, the genius (again, her words...lol).  Then she tells me the problem:

You sold tickets to a football game.  Kids' tickets were $4, and general admission tickets were $6.  You sold 525 tickets, totaling $2,876.  How many kids' and general admission tickets did you sell?

Now mind you, I haven't been in school in over 10 years...I had an idea how to get the answer, but nothing was clicking.  So I had to get help from where else, but the web?  I did finally get the answer:

x + y = 525
x = 525 - y
4x + 6y = 2876
4 (525 - y) + 6y = 2876
2100 - 4y + 6y = 2876
2y = 776
y = 388
x = 137

Just to make sure...
388 * 6 = 2328
137 * 4 = 548
2328 + 548 = 2876
YAY!

There's your lesson for the day...well, that and don't get the phone during AI.

til next time...=)
