35 of the remaining amount is the same as
47 of the total amount.
Amount that Adam has at first = 7 u
Amount that Adam spends on the marbles
= 9 u - 8 u
= 1 u
1 u = 270
Amount that Adam has at first
= 7 u
= 7 x 270
= $1890
(b)
Amount that Adam spends on stickers
= 8 u
= 8 x 270
= $2160
Amount that Adam spends more on stickers than on marbles
= 2160 - 270
= $1890
Answer(s): (a) $1890; (b) $1890
