Eric has $15. Wesley has $4
s more than Eric. Liam has $2
s less than Wesley.
- Find the amount of money that Liam has in terms of s.
- Find the total amount of money that the three boys have in terms of s.
- If s = 5, how much does Liam have?
(a)
Amount that Eric has = $15
Amount that Wesley has = $(15 + 4
s)
Amount that Liam has
= 15 + 4
s - 2
s = $(15 + 2
s)
(b)
Total amount that the three boys have
= 15 + 15 + 4
s + 15 + 2
s= 15 + 15 + 15 + 4
s + 2
s = $(45 + 6
s)
(c)
Amount that Liam has
= 15 + 2
s= 15 + 2 x 5
= 15 + 10
= $25
Answer(s): (a) $(15 + 2
s) or $(2
s + 15); (b) $(45 + 6
s) or $(6
s + 45); (c) $25
