Julian has $18. Owen has $4
q more than Julian. Sam has $2
q less than Owen.
- Find the amount of money that Sam has in terms of q.
- Find the total amount of money that the three boys have in terms of q.
- If q = 6, how much does Sam have?
(a)
Amount that Julian has = $18
Amount that Owen has = $(18 + 4
q)
Amount that Sam has
= 18 + 4
q - 2
q = $(18 + 2
q)
(b)
Total amount that the three boys have
= 18 + 18 + 4
q + 18 + 2
q= 18 + 18 + 18 + 4
q + 2
q = $(54 + 6
q)
(c)
Amount that Sam has
= 18 + 2
q= 18 + 2 x 6
= 18 + 12
= $30
Answer(s): (a) $(18 + 2
q) or $(2
q + 18); (b) $(54 + 6
q) or $(6
q + 54); (c) $30
