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 stickers
= 4 u - 3 u
= 1 u
1 u = 180
Amount that Adam has at first
= 4 u
= 4 x 180
= $720
(b)
Amount that Adam spends on beads
= 3 u
= 3 x 180
= $540
Amount that Adam spends more on beads than on stickers
= 540 - 180
= $360
Answer(s): (a) $720; (b) $360
