Seth has $18. Carl has $5
w more than Seth. Riordan has $2
w less than Carl.
- Find the amount of money that Riordan 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 Riordan have?
(a)
Amount that Seth has = $18
Amount that Carl has = $(18 + 5
w)
Amount that Riordan has
= 18 + 5
w - 2
w = $(18 + 3
w)
(b)
Total amount that the three boys have
= 18 + 18 + 5
w + 18 + 3
w= 18 + 18 + 18 + 5
w + 3
w = $(54 + 8
w)
(c)
Amount that Riordan has
= 18 + 3
w= 18 + 3 x 5
= 18 + 15
= $33
Answer(s): (a) $(18 + 3
w) or $(3
w + 18); (b) $(54 + 8
w) or $(8
w + 54); (c) $33
