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 marbles
= 9 u - 8 u
= 1 u
1 u = 190
Amount that Adam has at first
= 7 u
= 7 x 190
= $1330
(b)
Amount that Adam spends on beads
= 8 u
= 8 x 190
= $1520
Amount that Adam spends more on beads than on marbles
= 1520 - 190
= $1330
Answer(s): (a) $1330; (b) $1330
