Tina spent
311 of her money on some glues. She spent
18 of the remaining money on some punchers and
47 of what was left on some foolscaps.
- What fraction of her money was left?
- Given that the foolscaps cost $30 more than the punchers, find the sum of money that Tina had at first.

(a)
Fraction of money left after spending on the glues
= 1 -
311 =
811 Fraction of remaining money after spending on the punchers
= 1 -
18 =
78 Fraction of what was left after spending on the foolscaps
= 1 -
47 =
37 Fraction of money that was left =
311 (b)
Amount that Tina spent on the punchers = 1 u
Amount that Tina spent on the foolscaps = 4 u
Amount that the foolscaps cost more than the punchers
= 4 u - 1 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Tina had at first
= 11 u
= 11 x 10
= $110
Answer(s): (a)
311; (b) $110
