Liam has $19. Perry has $5
q more than Liam. Mark has $2
q less than Perry.
- Find the amount of money that Mark has in terms of q.
- Find the total amount of money that the three boys have in terms of q.
- If q = 7, how much does Mark have?
(a)
Amount that Liam has = $19
Amount that Perry has = $(19 + 5
q)
Amount that Mark has
= 19 + 5
q - 2
q = $(19 + 3
q)
(b)
Total amount that the three boys have
= 19 + 19 + 5
q + 19 + 3
q= 19 + 19 + 19 + 5
q + 3
q = $(57 + 8
q)
(c)
Amount that Mark has
= 19 + 3
q= 19 + 3 x 7
= 19 + 21
= $40
Answer(s): (a) $(19 + 3
q) or $(3
q + 19); (b) $(57 + 8
q) or $(8
q + 57); (c) $40
