Vincent has $8. Ryan has $5
k more than Vincent. David has $2
k less than Ryan.
- Find the amount of money that David 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 David have?
(a)
Amount that Vincent has = $8
Amount that Ryan has = $(8 + 5
k)
Amount that David has
= 8 + 5
k - 2
k = $(8 + 3
k)
(b)
Total amount that the three boys have
= 8 + 8 + 5
k + 8 + 3
k= 8 + 8 + 8 + 5
k + 3
k = $(24 + 8
k)
(c)
Amount that David has
= 8 + 3
k= 8 + 3 x 6
= 8 + 18
= $26
Answer(s): (a) $(8 + 3
k) or $(3
k + 8); (b) $(24 + 8
k) or $(8
k + 24); (c) $26
