Perry has $10. Howard has $4
z more than Perry. Tim has $2
z less than Howard.
- Find the amount of money that Tim 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 Tim have?
(a)
Amount that Perry has = $10
Amount that Howard has = $(10 + 4
z)
Amount that Tim has
= 10 + 4
z - 2
z = $(10 + 2
z)
(b)
Total amount that the three boys have
= 10 + 10 + 4
z + 10 + 2
z= 10 + 10 + 10 + 4
z + 2
z = $(30 + 6
z)
(c)
Amount that Tim has
= 10 + 2
z= 10 + 2 x 5
= 10 + 10
= $20
Answer(s): (a) $(10 + 2
z) or $(2
z + 10); (b) $(30 + 6
z) or $(6
z + 30); (c) $20
