George has $20. Fred has $5
c more than George. Valen has $2
c less than Fred.
- Find the amount of money that Valen has in terms of c.
- Find the total amount of money that the three boys have in terms of c.
- If c = 5, how much does Valen have?
(a)
Amount that George has = $20
Amount that Fred has = $(20 + 5
c)
Amount that Valen has
= 20 + 5
c - 2
c = $(20 + 3
c)
(b)
Total amount that the three boys have
= 20 + 20 + 5
c + 20 + 3
c= 20 + 20 + 20 + 5
c + 3
c = $(60 + 8
c)
(c)
Amount that Valen has
= 20 + 3
c= 20 + 3 x 5
= 20 + 15
= $35
Answer(s): (a) $(20 + 3
c) or $(3
c + 20); (b) $(60 + 8
c) or $(8
c + 60); (c) $35
