Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Bryan spends
211 of his money on some beads.
He spends
13 of his remaining money on some marbles.
- Amount that Bryan spends on the beads = _____ u
- Amount that Bryan spends on the marbles = _____ u
- Amount that Bryan has in the end = _____ u
- Difference in the amount spent on the marbles and beads = _____ u
(a)
Fraction of his money spent on the beads =

311Amount that Bryan spends on the beads = 2 u
(b)
Amount that Bryan spends on the marbles = 3 u
(c)
Amount that Bryan has in the end
= 11 u - 3 u - 2 u
= 6 u
(d)
Difference in the amount spent on the marbles and beads
= 3 u - 2 u
= 1 u
Answer(s): (a) 2; (b) 3; (c) 6; (d) 1
