Total : Spent : Left
5 : 1 : 5 - 1
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 beads
= 4 u - 3 u
= 1 u
1 u = 140
Amount that Adam has at first
= 4 u
= 4 x 140
= $560
(b)
Amount that Adam spends on marbles
= 3 u
= 3 x 140
= $420
Amount that Adam spends more on marbles than on beads
= 420 - 140
= $280
Answer(s): (a) $560; (b) $280
