Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Bryan spends
15 of his money on some marbles.
He spends
27 of his remaining money on some stickers.
- Amount that Bryan spends on the marbles = _____ u
- Amount that Bryan spends on the stickers = _____ u

835Amount that Bryan spends on the marbles = 7 u
(b)
Amount that Bryan spends on the stickers = 8 u
(c)
Amount that Bryan has in the end
= 35 u - 8 u - 7 u
= 20 u
(d)
Difference in the amount spent on the stickers and marbles
= 8 u - 7 u
= 1 u
Answer(s): (a) 7; (b) 8; (c) 20; (d) 1
