= 1 -
17 =
67 Fraction of remaining money after spending on the foolscaps

16 =
56 Fraction of what was left after spending on the pens
= 1 -
35 =
25 Fraction of money that was spent on pens =
37 (b)
Amount that Opal spent on the folders = 1 u
Amount that Opal spent on the pens = 3 u
Amount that the folders cost less than the pens
= 3 u - 1 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Amount that Opal sent
= 1 u + 1 u + 3 u
= 5 u
= 5 x 8
= $40
Answer(s): (a)
37; (b) $40
