Total : Spent : Left

4 : 1 : 3
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 beads
= 6 u - 5 u
= 1 u
1 u = 130
Amount that Adam has at first
= 7 u
= 7 x 130
= $910
(b)
Amount that Adam spends on marbles
= 5 u
= 5 x 130
= $650
Amount that Adam spends more on marbles than on beads
= 650 - 130
= $520
Answer(s): (a) $910; (b) $520
