Vaidev has $15. Henry has $4
c more than Vaidev. Cody has $2
c less than Henry.
- Find the amount of money that Cody has in terms of c.
- Find the total amount of money that the three boys have in terms of c.
- If c = 7, how much does Cody have?
(a)
Amount that Vaidev has = $15
Amount that Henry has = $(15 + 4
c)
Amount that Cody has
= 15 + 4
c - 2
c = $(15 + 2
c)
(b)
Total amount that the three boys have
= 15 + 15 + 4
c + 15 + 2
c= 15 + 15 + 15 + 4
c + 2
c = $(45 + 6
c)
(c)
Amount that Cody has
= 15 + 2
c= 15 + 2 x 7
= 15 + 14
= $29
Answer(s): (a) $(15 + 2
c) or $(2
c + 15); (b) $(45 + 6
c) or $(6
c + 45); (c) $29
