5 : 1 : 4
45 of the remaining amount is the same as
34 of the total amount.
Amount that Adam has at first = 4 u
Amount that Adam spends on the marbles
= 4 u - 3 u
= 1 u
1 u = 310
Amount that Adam has at first
= 4 u
= 4 x 310
= $1240
(b)
Amount that Adam spends on stickers
= 3 u
= 3 x 310
= $930
Amount that Adam spends more on stickers than on marbles
= 930 - 310
= $620
Answer(s): (a) $1240; (b) $620
