(a)
Fraction of money left after spending on the pens
= 1 -
211 =
911 Fraction of remaining money after spending on the markers
= 1 -
29 =
79 Fraction of what was left after spending on the files
= 1 -
47 =
37 Fraction of money that was spent on files =
411 (b)
Amount that Gwen spent on the pens = 2 u
Amount that Gwen spent on the files = 4 u
Amount that the pens cost less than the files
= 4 u - 2 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Amount that Gwen sent
= 2 u + 2 u + 4 u
= 8 u
= 8 x 7
= $56
Answer(s): (a)
411; (b) $56
