49 of the remaining money on some rulers and

(a)
Fraction of money left after spending on the markers
= 1 -
211 =
911 Fraction of remaining money after spending on the rulers
= 1 -
49 =
59 Fraction of what was left after spending on the staplers
= 1 -
45 =
15 Fraction of money that was spent on staplers =
411 (b)
Amount that Dana spent on the markers = 2 u
Amount that Dana spent on the staplers = 4 u
Amount that the markers cost less than the staplers
= 4 u - 2 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Amount that Dana sent
= 2 u + 4 u + 4 u
= 10 u
= 10 x 3
= $30
Answer(s): (a)
411; (b) $30
