(a)
Fraction of money left after spending on the foolscaps
= 1 -
17 =
67 Fraction of remaining money after spending on the punchers
= 1 -
16 =
56 Fraction of what was left after spending on the folders
= 1 -
35 =
25 Fraction of money that was spent on folders =
37 (b)
Amount that Eva spent on the foolscaps = 1 u
Amount that Eva spent on the folders = 3 u
Amount that the foolscaps cost less than the folders
= 3 u - 1 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Amount that Eva sent
= 1 u + 1 u + 3 u
= 5 u
= 5 x 2
= $10
Answer(s): (a)
37; (b) $10
