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

15391639 =
1639Amount that Charlie spends on the stickers = 15 u
(b)
Amount that Charlie spends on the beads = 16 u
(c)
Amount that Charlie has in the end
= 39 u - 16 u - 15 u
= 8 u
(d)
Difference in the amount spent on the beads and stickers
= 16 u - 15 u
= 1 u
Answer(s): (a) 15; (b) 16; (c) 8; (d) 1
