Henry has $14. Seth has $5
z more than Henry. Liam has $2
z less than Seth.
- Find the amount of money that Liam has in terms of z.
- Find the total amount of money that the three boys have in terms of z.
- If z = 5, how much does Liam have?
(a)
Amount that Henry has = $14
Amount that Seth has = $(14 + 5
z)
Amount that Liam has
= 14 + 5
z - 2
z = $(14 + 3
z)
(b)
Total amount that the three boys have
= 14 + 14 + 5
z + 14 + 3
z= 14 + 14 + 14 + 5
z + 3
z = $(42 + 8
z)
(c)
Amount that Liam has
= 14 + 3
z= 14 + 3 x 5
= 14 + 15
= $29
Answer(s): (a) $(14 + 3
z) or $(3
z + 14); (b) $(42 + 8
z) or $(8
z + 42); (c) $29
