Pierre has $16. Archie has $4
t more than Pierre. Tommy has $2
t less than Archie.
- Find the amount of money that Tommy has in terms of t.
- Find the total amount of money that the three boys have in terms of t.
- If t = 7, how much does Tommy have?
(a)
Amount that Pierre has = $16
Amount that Archie has = $(16 + 4
t)
Amount that Tommy has
= 16 + 4
t - 2
t = $(16 + 2
t)
(b)
Total amount that the three boys have
= 16 + 16 + 4
t + 16 + 2
t= 16 + 16 + 16 + 4
t + 2
t = $(48 + 6
t)
(c)
Amount that Tommy has
= 16 + 2
t= 16 + 2 x 7
= 16 + 14
= $30
Answer(s): (a) $(16 + 2
t) or $(2
t + 16); (b) $(48 + 6
t) or $(6
t + 48); (c) $30
