Tina spent
110 of her money on some glues. She spent
29 of the remaining money on some folders and
37 of what was left on some foolscaps.
- What fraction of her money was spent on foolscaps?
- Given that the glues cost $4 less than the foolscaps, find the sum of money that Tina spent.

(a)
Fraction of money left after spending on the glues
= 1 -
110 =
910 Fraction of remaining money after spending on the folders
= 1 -
29 =
79 Fraction of what was left after spending on the foolscaps
= 1 -
37 =
47 Fraction of money that was spent on foolscaps =
310 (b)
Amount that Tina spent on the glues = 1 u
Amount that Tina spent on the foolscaps = 3 u
Amount that the glues cost less than the foolscaps
= 3 u - 1 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Amount that Tina sent
= 1 u + 2 u + 3 u
= 6 u
= 6 x 2
= $12
Answer(s): (a)
310; (b) $12
