15 of his money on some marbles.
He spends
38 of his remaining money on some stickers.
- Amount that Adam spends on the marbles = _____ u
- Amount that Adam spends on the stickers = _____ u

(b)
Amount that Adam spends on the stickers = 3 u
(c)
Amount that Adam has in the end
= 10 u - 3 u - 2 u
= 5 u

Difference in the amount spent on the stickers and marbles
= 3 u - 2 u
= 1 u
