(a)
Fraction of money left after spending on the rulers
= 1 -
211 =
911 Fraction of remaining money after spending on the markers
= 1 -
29 =
79 Fraction of what was left after spending on the highlighters
= 1 -
47 =
37 Fraction of money that was left =
311 (b)
Amount that Gillian spent on the markers = 2 u
Amount that Gillian spent on the highlighters = 4 u
Amount that the highlighters cost more than the markers
= 4 u - 2 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Amount that Gillian had at first
= 11 u
= 11 x 6
= $66
Answer(s): (a)
311; (b) $66
