Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
215 of his money on some marbles.
He spends
27 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 =
215 Fraction of his money left after spending on the marbles
= 1 -
215=

1410526105 =
26105Amount that Charlie spends on the marbles = 14 u
(b)
Amount that Charlie spends on the beads = 26 u
(c)
Amount that Charlie has in the end
= 105 u - 26 u - 14 u
= 65 u
(d)
Difference in the amount spent on the beads and marbles
= 26 u - 14 u
= 12 u
Answer(s): (a) 14; (b) 26; (c) 65; (d) 12
