Total : Spent : Left
10 : 1 : 10 - 1
10 : 1 : 9
910 of the remaining amount is the same as
56 of the total amount.
Amount that Adam has at first = 6 u
Amount that Adam spends on the stickers
= 9 u - 5 u
= 4 u
4 u = 160
1 u = 160 ÷ 4 = 40
Amount that Adam has at first
= 6 u
= 6 x 40
= $240
(b)
Amount that Adam spends on marbles
= 5 u
= 5 x 40
= $200
Amount that Adam spends more on marbles than on stickers
= 200 - 160
= $40
Answer(s): (a) $240; (b) $40
