Nick has $9. Charlie has $5
t more than Nick. Reggie has $2
t less than Charlie.
- Find the amount of money that Reggie has in terms of t.
- Find the total amount of money that the three boys have in terms of t.
- If t = 5, how much does Reggie have?
(a)
Amount that Nick has = $9
Amount that Charlie has = $(9 + 5
t)
Amount that Reggie has
= 9 + 5
t - 2
t = $(9 + 3
t)
(b)
Total amount that the three boys have
= 9 + 9 + 5
t + 9 + 3
t= 9 + 9 + 9 + 5
t + 3
t = $(27 + 8
t)
(c)
Amount that Reggie has
= 9 + 3
t= 9 + 3 x 5
= 9 + 15
= $24
Answer(s): (a) $(9 + 3
t) or $(3
t + 9); (b) $(27 + 8
t) or $(8
t + 27); (c) $24
