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

1128Amount that Charlie spends on the marbles = 6 u
(b)
Amount that Charlie spends on the stickers = 11 u
(c)
Amount that Charlie has in the end
= 28 u - 11 u - 6 u
= 11 u
(d)
Difference in the amount spent on the stickers and marbles
= 11 u - 6 u
= 5 u
Answer(s): (a) 6; (b) 11; (c) 11; (d) 5
