Question 85992: 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? Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! (X-.5)*2X/3*3X/4=7777
.5X*2X/3*3X/4=7777
.25X=7777
X=7777/.25
X=31108 IS HER TOTAL ANNUAL ALLOWANCE.
31108/12=2592.33 IS HER MONTHLY ALLOWANCE.
