5 : 2 : 3
35 of the remaining amount is the same as
47 of the total amount.
Amount that Adam has at first = 7 u
Amount that Adam spends on the beads
= 9 u - 8 u
= 1 u
1 u = 390
Amount that Adam has at first
= 7 u
= 7 x 390
= $2730
(b)
Amount that Adam spends on marbles
= 8 u
= 8 x 390
= $3120
Amount that Adam spends more on marbles than on beads
= 3120 - 390
= $2730
Answer(s): (a) $2730; (b) $2730
