Sean has $19. Neave has $4
z more than Sean. Caden has $2
z less than Neave.
- Find the amount of money that Caden has in terms of z.
- Find the total amount of money that the three boys have in terms of z.
- If z = 6, how much does Caden have?
(a)
Amount that Sean has = $19
Amount that Neave has = $(19 + 4
z)
Amount that Caden has
= 19 + 4
z - 2
z = $(19 + 2
z)
(b)
Total amount that the three boys have
= 19 + 19 + 4
z + 19 + 2
z= 19 + 19 + 19 + 4
z + 2
z = $(57 + 6
z)
(c)
Amount that Caden has
= 19 + 2
z= 19 + 2 x 6
= 19 + 12
= $31
Answer(s): (a) $(19 + 2
z) or $(2
z + 19); (b) $(57 + 6
z) or $(6
z + 57); (c) $31
