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

2765Amount that Charlie spends on the marbles = 20 u
(b)
Amount that Charlie spends on the stickers = 27 u
(c)
Amount that Charlie has in the end
= 65 u - 27 u - 20 u
= 18 u
(d)
Difference in the amount spent on the stickers and marbles
= 27 u - 20 u
= 7 u
Answer(s): (a) 20; (b) 27; (c) 18; (d) 7
