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?

I'm not going to give you the answer, but try this. Add up all the fractions together first.

I figured it out... But I need help on this math question...

If 1/2x +1/2(1/2x + 1/2(1/2x +1/2(1/2x + ... = y,
then x = ?

Also, try adding 1/4+1/2+1/3 cause what you posted before is incorrect.

1/4 1/2 1/3? hmm least common denominator is 12. so 4x3= 12 1x3= 3 so 3/12. 1/2 would be 2x6 =12 1x6= 6 6/12. and 1/3 would be 3x4=12 1x4=4 so 4/12. add 3/12 6/12 and 4/12 you get 13/12. so No Solution, because that is over 100% hop that helped!

p.s, 900th post is next, where to put it?

@Tucker118

No, you have 1/2. Then you have 1/3 of a 1/2. Then you have 1/4 of 1/6.

your least common denominator of all of them is 12... 1/2 = 6/12, 1/3 =4/12 and 1/4= 3/12. 6+4+3= 13 so 13/12 it's over 100% so there is no way she had 100 and some od percent of allowance, when she could only have 100% of her allowance.

@tucker

the question was how much money does she earn every month?

my answer: (X-.5)*2X/3*3X/4=7777
.5X*2X/3*3X/4=7777
.25X=7777
X=7777/.25
X=31108
31108/12=2592.33 is her monthly allowance


Your answer:
so No Solution, because that is over 100%

Ya I think I'm right.....And I hope you like grade 9 trigonometry cause looks like you might be repeating it XD
