Alright, I don't particularly mind math, and I suppose I'm good at it as I am in an honors class. But I'm too young to have had all the hard math you;ve been talking about. But, here's a problem for you.

Every month, a girl gets allowance. Assume last year she had no money, and kept it up to now. Then she spends 1/2 of her money on clothes, then 1/3 of the remaining money on games, and then 1/4 of the remaining money on toys. After she bought all of that, she had $7777 left. Assuming she only gets money by allowance, how much money does she earn every month?
