John has $19. Andy has $4
q more than John. Tommy has $2
q less than Andy.
- Find the amount of money that Tommy 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 Tommy have?
(a)
Amount that John has = $19
Amount that Andy has = $(19 + 4
q)
Amount that Tommy has
= 19 + 4
q - 2
q = $(19 + 2
q)
(b)
Total amount that the three boys have
= 19 + 19 + 4
q + 19 + 2
q= 19 + 19 + 19 + 4
q + 2
q = $(57 + 6
q)
(c)
Amount that Tommy has
= 19 + 2
q= 19 + 2 x 5
= 19 + 10
= $29
Answer(s): (a) $(19 + 2
q) or $(2
q + 19); (b) $(57 + 6
q) or $(6
q + 57); (c) $29
