Perry has $10. Warren has $5
q more than Perry. Vaidev has $2
q less than Warren.
- Find the amount of money that Vaidev 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 Vaidev have?
(a)
Amount that Perry has = $10
Amount that Warren has = $(10 + 5
q)
Amount that Vaidev has
= 10 + 5
q - 2
q = $(10 + 3
q)
(b)
Total amount that the three boys have
= 10 + 10 + 5
q + 10 + 3
q= 10 + 10 + 10 + 5
q + 3
q = $(30 + 8
q)
(c)
Amount that Vaidev has
= 10 + 3
q= 10 + 3 x 7
= 10 + 21
= $31
Answer(s): (a) $(10 + 3
q) or $(3
q + 10); (b) $(30 + 8
q) or $(8
q + 30); (c) $31
