This is hardly calculus.
Assume the original money was in 24 parts. She spent 12 parts on clothes, she had 12 parts left. She spent 4 parts on games. She had 8 parts left. She spend 2 parts on toys. She had six parts left.
sixparts is 7777. What is the original 24 parts?
Ok, it is prealgebra, not calculus.
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?
