34 of the remaining amount is the same as
57 of the total amount.
Amount that Adam has at first = 7 u
Amount that Adam spends on the marbles
= 6 u - 5 u
= 1 u
1 u = 230
Amount that Adam has at first
= 7 u
= 7 x 230
= $1610
(b)
Amount that Adam spends on stickers
= 5 u
= 5 x 230
= $1150
Amount that Adam spends more on stickers than on marbles
= 1150 - 230
= $920
Answer(s): (a) $1610; (b) $920
