(a)
Fraction of money left after spending on the rulers
= 1 -
29 =
79 Fraction of remaining money after spending on the foolscaps
= 1 -
27 =
57 Fraction of what was left after spending on the punchers
= 1 -
45 =
15 Fraction of money that was left =
19 (b)
Amount that Jaslyn spent on the foolscaps = 2 u
Amount that Jaslyn spent on the punchers = 4 u
Amount that the punchers cost more than the foolscaps
= 4 u - 2 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Amount that Jaslyn had at first
= 9 u
= 9 x 3
= $27
Answer(s): (a)
19; (b) $27
