John has $15. Zane has $4
b more than John. Vaidev has $2
b less than Zane.
- Find the amount of money that Vaidev has in terms of b.
- Find the total amount of money that the three boys have in terms of b.
- If b = 5, how much does Vaidev have?
(a)
Amount that John has = $15
Amount that Zane has = $(15 + 4
b)
Amount that Vaidev has
= 15 + 4
b - 2
b = $(15 + 2
b)
(b)
Total amount that the three boys have
= 15 + 15 + 4
b + 15 + 2
b= 15 + 15 + 15 + 4
b + 2
b = $(45 + 6
b)
(c)
Amount that Vaidev has
= 15 + 2
b= 15 + 2 x 5
= 15 + 10
= $25
Answer(s): (a) $(15 + 2
b) or $(2
b + 15); (b) $(45 + 6
b) or $(6
b + 45); (c) $25
