Jenson has $8. Zeph has $4
z more than Jenson. Elijah has $2
z less than Zeph.
- Find the amount of money that Elijah 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 Elijah have?
(a)
Amount that Jenson has = $8
Amount that Zeph has = $(8 + 4
z)
Amount that Elijah has
= 8 + 4
z - 2
z = $(8 + 2
z)
(b)
Total amount that the three boys have
= 8 + 8 + 4
z + 8 + 2
z= 8 + 8 + 8 + 4
z + 2
z = $(24 + 6
z)
(c)
Amount that Elijah has
= 8 + 2
z= 8 + 2 x 5
= 8 + 10
= $18
Answer(s): (a) $(8 + 2
z) or $(2
z + 8); (b) $(24 + 6
z) or $(6
z + 24); (c) $18
