Victoria and Billy collect marbles and stickers. Billy has 88 less marbles than stickers. Billy has 3 times the number of marbles Victoria has, and Victoria has 25% more stickers than Billy. After Victoria gives Billy all of her marbles and Billy gives Victoria 75% of his stickers, Billy has 4 more marbles than stickers. Find the number of stickers Victoria has at first.

Victoria		Billy
Stickers	Marbles	Stickers	Marbles
3.75 u + 110	1 u	3 u + 88	3 u
+ 2.25 u + 66	- 1 u	- 2.25 u - 66	+ 1 u
6 u + 176	0	0.75 u + 22	4 u

100%+ 25% = 125% 

125% x 3 u
= ¹²⁵₁₀₀ x 3 u
= 3.75 u

125% x 88
= ¹²⁵₁₀₀ x 88
= 110 

75% x 3 u
= ⁷⁵₁₀₀ x 3 u
= 2.25 u  

75% x 88 
= ⁷⁵₁₀₀ x 88
= 66 

If another 4 stickers are given to Billy, he will have equal number of stickers and marbles in the end.
4 u = 0.75 u + 22 + 4
4 u - 0.75 u = 26
3.25 u = 26

1 u = 26 ÷ 3.25 = 8

Number of stickers that Victoria has at first
= 3.75 u + 110
= 3.75 x 8 + 110
= 30 + 110
= 140
 
Answer(s): 140
