Nicole spent
310 of her money on some pens. She spent
27 of the remaining money on some correction tapes and
45 of what was left on some glues.
- What fraction of her money was left?
- Given that the glues cost $4 more than the correction tapes, find the sum of money that Nicole had at first.

(a)
Fraction of money left after spending on the pens
= 1 -
310 =
710 Fraction of remaining money after spending on the correction tapes
= 1 -
27 =
57 Fraction of what was left after spending on the glues
= 1 -
45 =
15 Fraction of money that was left =
110 (b)
Amount that Nicole spent on the correction tapes = 2 u
Amount that Nicole spent on the glues = 4 u
Amount that the glues cost more than the correction tapes
= 4 u - 2 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Amount that Nicole had at first
= 10 u
= 10 x 2
= $20
Answer(s): (a)
110; (b) $20
