13 of his money on 4 stickers and 3 beads.
Each bead costs four times as much as each sticker.
Let the price of 1 sticker be 1 u.
- Cost of 1 bead = _____ u
- Amount that Abdul has spent = _____ u

- Amount that Abdul has at first = _____ u
(a)
Change X times into units.
Cost of 1 sticker = 1 u
Cost of 1 bead = 4 x 1 u = 4 u
(b)
Amount that Abdul has spent

= 4 u + 12 u
= 16 u
(c)
Fraction of the money he has left
= 1 -
13 =
23 13 of his money = 16 u
23 of his money = 2 x 16 u = 32 u
Amount that Abdul has left = 32 u
(d)
Amount that Abdul has at first
= 16 u + 32 u
= 48 u
Answer(s): (a) 4; (b) 16; (c) 32; (d) 48
