(a)
Fraction of money left after spending on the punchers
= 1 -
29 =
79 Fraction of remaining money after spending on the folders
= 1 -
27 =
57 Fraction of what was left after spending on the glues
= 1 -
45 =
15 Fraction of money that was left =
19 (b)
Amount that Kathy spent on the folders = 2 u
Amount that Kathy spent on the glues = 4 u
Amount that the glues cost more than the folders
= 4 u - 2 u
= 2 u
2 u = 18
1 u = 18 ÷ 2 = 9
Amount that Kathy had at first
= 9 u
= 9 x 9
= $81
Answer(s): (a)
19; (b) $81
