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