37 Fraction of money that was left =
311 (b)
Amount that Raeann spent on the folders = 2 u
Amount that Raeann spent on the rulers = 4 u
Amount that the rulers cost more than the folders
= 4 u - 2 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Amount that Raeann had at first
= 11 u
= 11 x 6
= $66
Answer(s): (a)
311; (b) $66
