(a)
Fraction of money left after spending on the pens
= 1 -
213 =
1113 Fraction of remaining money after spending on the highlighters
= 1 -
411 =
711 Fraction of what was left after spending on the files
= 1 -
47 =
37 Fraction of money that was spent on files =
413 (b)
Amount that Cindy spent on the pens = 2 u
Amount that Cindy spent on the files = 4 u
Amount that the pens cost less than the files
= 4 u - 2 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Amount that Cindy sent
= 2 u + 4 u + 4 u
= 10 u
= 10 x 3
= $30
Answer(s): (a)
413; (b) $30
