(a)
Amount left after Adam spends on some marbles and beads
= 1 -
57 -
18 =
5656 -
4056 -
756 =
956 956 of total amount =
99 of the remaining amount
Total amount = 56 u
Amount left = 9 u - 7 u = 2 u
2 u = 100
1 u = 100 ÷ 2 = 50
Amount that he spends on the marbles
= 40 u
= 40 x 50
= $2000
(b)
Amount that he spends on the beads
= 7 u
= 7 x 50
= $350
(c)
Amount that he spends on the stickers
= 7 u
= 7 x 50
= $350
(d)
Amount that he spends altogether
= 2000 + 350 + 350
= $2700
Answer(s): (a) $2000; (b) $350; (c) $350; (d) $2700
