Ian has $19. Oliver has $4
t more than Ian. Seth has $2
t less than Oliver.
- Find the amount of money that Seth 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 Seth have?
(a)
Amount that Ian has = $19
Amount that Oliver has = $(19 + 4
t)
Amount that Seth has
= 19 + 4
t - 2
t = $(19 + 2
t)
(b)
Total amount that the three boys have
= 19 + 19 + 4
t + 19 + 2
t= 19 + 19 + 19 + 4
t + 2
t = $(57 + 6
t)
(c)
Amount that Seth has
= 19 + 2
t= 19 + 2 x 5
= 19 + 10
= $29
Answer(s): (a) $(19 + 2
t) or $(2
t + 19); (b) $(57 + 6
t) or $(6
t + 57); (c) $29
