Fiona spent 60% of her money on a number of marbles. She spent 15% of the remaining money on a few cards and 50% of what was left on a number of erasers.
- What fraction of her money was left?

60100Amount spent more on the marbles than the erasers
= 60 u - 17 u
= 43 u
43 u = 86
1 u = 86 ÷ 43 = 2
Amount that Fiona had at first
= 100 u
= 100 x 2
= $200
Answer(s): (a)
17100; (b) $200
