18 of the remaining money on some foolscaps and
37 of what was left on some rulers.

(a)
Fraction of money left after spending on the pens
= 1 -
19 =
89 Fraction of remaining money after spending on the foolscaps
= 1 -
18 =
78 Fraction of what was left after spending on the rulers
= 1 -
37 =
47 Fraction of money that was left =
49 (b)
Amount that Nicole spent on the foolscaps = 1 u
Amount that Nicole spent on the rulers = 3 u
Amount that the rulers cost more than the foolscaps
= 3 u - 1 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Amount that Nicole had at first
= 9 u
= 9 x 9
= $81
Answer(s): (a)
49; (b) $81
