He spends
34 of his remaining money on some stickers.
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie spends on the stickers = _____ u

- Difference in the amount spent on the stickers and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
314 Fraction of his money left after spending on the marbles
= 1 -
314=
1114 Fraction of his money spent on the stickers
=
1114 x

12563356 =
3356Amount that Charlie spends on the marbles = 12 u
(b)
Amount that Charlie spends on the stickers = 33 u
(c)
Amount that Charlie has in the end
= 56 u - 33 u - 12 u
= 11 u
(d)
Difference in the amount spent on the stickers and marbles
= 33 u - 12 u
= 21 u
Answer(s): (a) 12; (b) 33; (c) 11; (d) 21
