Bryan has $18. Fred has $5
q more than Bryan. Billy has $2
q less than Fred.
- Find the amount of money that Billy has in terms of q.
- Find the total amount of money that the three boys have in terms of q.
- If q = 5, how much does Billy have?
(a)
Amount that Bryan has = $18
Amount that Fred has = $(18 + 5
q)
Amount that Billy has
= 18 + 5
q - 2
q = $(18 + 3
q)
(b)
Total amount that the three boys have
= 18 + 18 + 5
q + 18 + 3
q= 18 + 18 + 18 + 5
q + 3
q = $(54 + 8
q)
(c)
Amount that Billy has
= 18 + 3
q= 18 + 3 x 5
= 18 + 15
= $33
Answer(s): (a) $(18 + 3
q) or $(3
q + 18); (b) $(54 + 8
q) or $(8
q + 54); (c) $33
