Andy has $15. Vincent has $5
k more than Andy. Owen has $2
k less than Vincent.
- Find the amount of money that Owen has in terms of k.
- Find the total amount of money that the three boys have in terms of k.
- If k = 6, how much does Owen have?
(a)
Amount that Andy has = $15
Amount that Vincent has = $(15 + 5
k)
Amount that Owen has
= 15 + 5
k - 2
k = $(15 + 3
k)
(b)
Total amount that the three boys have
= 15 + 15 + 5
k + 15 + 3
k= 15 + 15 + 15 + 5
k + 3
k = $(45 + 8
k)
(c)
Amount that Owen has
= 15 + 3
k= 15 + 3 x 6
= 15 + 18
= $33
Answer(s): (a) $(15 + 3
k) or $(3
k + 15); (b) $(45 + 8
k) or $(8
k + 45); (c) $33
