Julian has $9. Brandon has $5
s more than Julian. Ian has $2
s less than Brandon.
- Find the amount of money that Ian has in terms of s.
- Find the total amount of money that the three boys have in terms of s.
- If s = 4, how much does Ian have?
(a)
Amount that Julian has = $9
Amount that Brandon has = $(9 + 5
s)
Amount that Ian has
= 9 + 5
s - 2
s = $(9 + 3
s)
(b)
Total amount that the three boys have
= 9 + 9 + 5
s + 9 + 3
s= 9 + 9 + 9 + 5
s + 3
s = $(27 + 8
s)
(c)
Amount that Ian has
= 9 + 3
s= 9 + 3 x 4
= 9 + 12
= $21
Answer(s): (a) $(9 + 3
s) or $(3
s + 9); (b) $(27 + 8
s) or $(8
s + 27); (c) $21
