Carl has $19. Henry has $4
c more than Carl. Vaidev has $2
c less than Henry.
- Find the amount of money that Vaidev 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 Vaidev have?
(a)
Amount that Carl has = $19
Amount that Henry has = $(19 + 4
c)
Amount that Vaidev has
= 19 + 4
c - 2
c = $(19 + 2
c)
(b)
Total amount that the three boys have
= 19 + 19 + 4
c + 19 + 2
c= 19 + 19 + 19 + 4
c + 2
c = $(57 + 6
c)
(c)
Amount that Vaidev has
= 19 + 2
c= 19 + 2 x 7
= 19 + 14
= $33
Answer(s): (a) $(19 + 2
c) or $(2
c + 19); (b) $(57 + 6
c) or $(6
c + 57); (c) $33
