Xavier has $17. Eric has $5
w more than Xavier. Vaidev has $2
w less than Eric.
- Find the amount of money that Vaidev has in terms of w.
- Find the total amount of money that the three boys have in terms of w.
- If w = 4, how much does Vaidev have?
(a)
Amount that Xavier has = $17
Amount that Eric has = $(17 + 5
w)
Amount that Vaidev has
= 17 + 5
w - 2
w = $(17 + 3
w)
(b)
Total amount that the three boys have
= 17 + 17 + 5
w + 17 + 3
w= 17 + 17 + 17 + 5
w + 3
w = $(51 + 8
w)
(c)
Amount that Vaidev has
= 17 + 3
w= 17 + 3 x 4
= 17 + 12
= $29
Answer(s): (a) $(17 + 3
w) or $(3
w + 17); (b) $(51 + 8
w) or $(8
w + 51); (c) $29
