Xavier has $18. Seth has $4
t more than Xavier. Perry has $2
t less than Seth.
- Find the amount of money that Perry 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 Perry have?
(a)
Amount that Xavier has = $18
Amount that Seth has = $(18 + 4
t)
Amount that Perry has
= 18 + 4
t - 2
t = $(18 + 2
t)
(b)
Total amount that the three boys have
= 18 + 18 + 4
t + 18 + 2
t= 18 + 18 + 18 + 4
t + 2
t = $(54 + 6
t)
(c)
Amount that Perry has
= 18 + 2
t= 18 + 2 x 5
= 18 + 10
= $28
Answer(s): (a) $(18 + 2
t) or $(2
t + 18); (b) $(54 + 6
t) or $(6
t + 54); (c) $28
