Billy has $19. Xavier has $4
t more than Billy. Fred has $2
t less than Xavier.
- Find the amount of money that Fred 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 Fred have?
(a)
Amount that Billy has = $19
Amount that Xavier has = $(19 + 4
t)
Amount that Fred 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 Fred 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
