Charlie has $11. John has $4
w more than Charlie. Xavier has $2
w less than John.
- Find the amount of money that Xavier 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 Xavier have?
(a)
Amount that Charlie has = $11
Amount that John has = $(11 + 4
w)
Amount that Xavier has
= 11 + 4
w - 2
w = $(11 + 2
w)
(b)
Total amount that the three boys have
= 11 + 11 + 4
w + 11 + 2
w= 11 + 11 + 11 + 4
w + 2
w = $(33 + 6
w)
(c)
Amount that Xavier has
= 11 + 2
w= 11 + 2 x 4
= 11 + 8
= $19
Answer(s): (a) $(11 + 2
w) or $(2
w + 11); (b) $(33 + 6
w) or $(6
w + 33); (c) $19
