Zeph has $8. Riordan has $5
t more than Zeph. Gabriel has $2
t less than Riordan.
- Find the amount of money that Gabriel has in terms of t.
- Find the total amount of money that the three boys have in terms of t.
- If t = 4, how much does Gabriel have?
(a)
Amount that Zeph has = $8
Amount that Riordan has = $(8 + 5
t)
Amount that Gabriel has
= 8 + 5
t - 2
t = $(8 + 3
t)
(b)
Total amount that the three boys have
= 8 + 8 + 5
t + 8 + 3
t= 8 + 8 + 8 + 5
t + 3
t = $(24 + 8
t)
(c)
Amount that Gabriel has
= 8 + 3
t= 8 + 3 x 4
= 8 + 12
= $20
Answer(s): (a) $(8 + 3
t) or $(3
t + 8); (b) $(24 + 8
t) or $(8
t + 24); (c) $20
