He spends
35 of his remaining money on some stickers.
- Amount that Bryan spends on the marbles = _____ u
- Amount that Bryan spends on the stickers = _____ u
- Amount that Bryan has in the end = _____ u
- Difference in the amount spent on the stickers and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
310 Fraction of his money left after spending on the marbles
= 1 -
310=
710 Fraction of his money spent on the stickers
=

2150Amount that Bryan spends on the marbles = 15 u
(b)
Amount that Bryan spends on the stickers = 21 u
(c)
Amount that Bryan has in the end
= 50 u - 21 u - 15 u
= 14 u
(d)
Difference in the amount spent on the stickers and marbles
= 21 u - 15 u
= 6 u
Answer(s): (a) 15; (b) 21; (c) 14; (d) 6
