Sean has $16. Reggie has $5
s more than Sean. Justin has $2
s less than Reggie.
- Find the amount of money that Justin 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 Justin have?
(a)
Amount that Sean has = $16
Amount that Reggie has = $(16 + 5
s)
Amount that Justin has
= 16 + 5
s - 2
s = $(16 + 3
s)
(b)
Total amount that the three boys have
= 16 + 16 + 5
s + 16 + 3
s= 16 + 16 + 16 + 5
s + 3
s = $(48 + 8
s)
(c)
Amount that Justin has
= 16 + 3
s= 16 + 3 x 5
= 16 + 15
= $31
Answer(s): (a) $(16 + 3
s) or $(3
s + 16); (b) $(48 + 8
s) or $(8
s + 48); (c) $31
