2 : 1 : 1
12 of the remaining amount is the same as
37 of the total amount.
Amount that Adam has at first = 7 u
Amount that Adam spends on the stickers
= 4 u - 3 u
= 1 u
1 u = 220
Amount that Adam has at first
= 7 u
= 7 x 220
= $1540
(b)
Amount that Adam spends on beads
= 3 u
= 3 x 220
= $660
Amount that Adam spends more on beads than on stickers
= 660 - 220
= $440
Answer(s): (a) $1540; (b) $440
