Bryan has $13. Sean has $5
s more than Bryan. Michael has $2
s less than Sean.
- Find the amount of money that Michael 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 Michael have?
(a)
Amount that Bryan has = $13
Amount that Sean has = $(13 + 5
s)
Amount that Michael has
= 13 + 5
s - 2
s = $(13 + 3
s)
(b)
Total amount that the three boys have
= 13 + 13 + 5
s + 13 + 3
s= 13 + 13 + 13 + 5
s + 3
s = $(39 + 8
s)
(c)
Amount that Michael has
= 13 + 3
s= 13 + 3 x 4
= 13 + 12
= $25
Answer(s): (a) $(13 + 3
s) or $(3
s + 13); (b) $(39 + 8
s) or $(8
s + 39); (c) $25
