Perry has $20. Julian has $5
q more than Perry. Justin has $2
q less than Julian.
- Find the amount of money that Justin has in terms of q.
- Find the total amount of money that the three boys have in terms of q.
- If q = 4, how much does Justin have?
(a)
Amount that Perry has = $20
Amount that Julian has = $(20 + 5
q)
Amount that Justin has
= 20 + 5
q - 2
q = $(20 + 3
q)
(b)
Total amount that the three boys have
= 20 + 20 + 5
q + 20 + 3
q= 20 + 20 + 20 + 5
q + 3
q = $(60 + 8
q)
(c)
Amount that Justin has
= 20 + 3
q= 20 + 3 x 4
= 20 + 12
= $32
Answer(s): (a) $(20 + 3
q) or $(3
q + 20); (b) $(60 + 8
q) or $(8
q + 60); (c) $32
