Kylie spent
17 of her money on some pens. She spent
16 of the remaining money on some highlighters and
35 of what was left on some glues.
- What fraction of her money was left?
- Given that the glues cost $12 more than the highlighters, find the sum of money that Kylie had at first.

(a)
Fraction of money left after spending on the pens
= 1 -
17 =
67 Fraction of remaining money after spending on the highlighters
= 1 -
16 =
56 Fraction of what was left after spending on the glues
= 1 -
35 =
25 Fraction of money that was left =
27 (b)
Amount that Kylie spent on the highlighters = 1 u
Amount that Kylie spent on the glues = 3 u
Amount that the glues cost more than the highlighters
= 3 u - 1 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Amount that Kylie had at first
= 7 u
= 7 x 6
= $42
Answer(s): (a)
27; (b) $42
