(a)
Fraction of money left after spending on the highlighters
= 1 -
16 =
56 Fraction of remaining money after spending on the markers
= 1 -
15 =
45 Fraction of what was left after spending on the post-it pads
= 1 -
34 =
14 Fraction of money that was left =
16 (b)
Amount that Gwen spent on the markers = 1 u
Amount that Gwen spent on the post-it pads = 3 u
Amount that the post-it pads cost more than the markers
= 3 u - 1 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Amount that Gwen had at first
= 6 u
= 6 x 4
= $24
Answer(s): (a)
16; (b) $24
