John has $12. Oliver has $4
w more than John. Ben has $2
w less than Oliver.
- Find the amount of money that Ben has in terms of w.
- Find the total amount of money that the three boys have in terms of w.
- If w = 5, how much does Ben have?
(a)
Amount that John has = $12
Amount that Oliver has = $(12 + 4
w)
Amount that Ben has
= 12 + 4
w - 2
w = $(12 + 2
w)
(b)
Total amount that the three boys have
= 12 + 12 + 4
w + 12 + 2
w= 12 + 12 + 12 + 4
w + 2
w = $(36 + 6
w)
(c)
Amount that Ben has
= 12 + 2
w= 12 + 2 x 5
= 12 + 10
= $22
Answer(s): (a) $(12 + 2
w) or $(2
w + 12); (b) $(36 + 6
w) or $(6
w + 36); (c) $22
