Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
15 of his money on some marbles.
He spends
35 of his remaining money on some beads.
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie spends on the beads = _____ u
- Amount that Charlie has in the end = _____ u
- Difference in the amount spent on the beads and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
15 Fraction of his money left after spending on the marbles
= 1 -

15 =
5251225 =
1225Amount that Charlie spends on the marbles = 5 u
(b)
Amount that Charlie spends on the beads = 12 u
(c)
Amount that Charlie has in the end
= 25 u - 12 u - 5 u
= 8 u
(d)
Difference in the amount spent on the beads and marbles
= 12 u - 5 u
= 7 u
Answer(s): (a) 5; (b) 12; (c) 8; (d) 7
