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
12 of his remaining money on some stickers.
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie spends on the stickers = _____ u
- Amount that Charlie has in the end = _____ u
- Difference in the amount spent on the stickers 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=
1315 Fraction of his money spent on the stickers
=
1315 x

215 =
4301330 =
1330Amount that Charlie spends on the marbles = 4 u
(b)
Amount that Charlie spends on the stickers = 13 u
(c)
Amount that Charlie has in the end
= 30 u - 13 u - 4 u
= 13 u
(d)
Difference in the amount spent on the stickers and marbles
= 13 u - 4 u
= 9 u
Answer(s): (a) 4; (b) 13; (c) 13; (d) 9
