Vaidev has $8. Justin has $4
q more than Vaidev. Zeph has $2
q less than Justin.
- Find the amount of money that Zeph 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 Zeph have?
(a)
Amount that Vaidev has = $8
Amount that Justin has = $(8 + 4
q)
Amount that Zeph has
= 8 + 4
q - 2
q = $(8 + 2
q)
(b)
Total amount that the three boys have
= 8 + 8 + 4
q + 8 + 2
q= 8 + 8 + 8 + 4
q + 2
q = $(24 + 6
q)
(c)
Amount that Zeph has
= 8 + 2
q= 8 + 2 x 4
= 8 + 8
= $16
Answer(s): (a) $(8 + 2
q) or $(2
q + 8); (b) $(24 + 6
q) or $(6
q + 24); (c) $16
