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