Tommy has $14. Billy has $4
z more than Tommy. Luke has $2
z less than Billy.
- Find the amount of money that Luke 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 Luke have?
(a)
Amount that Tommy has = $14
Amount that Billy has = $(14 + 4
z)
Amount that Luke has
= 14 + 4
z - 2
z = $(14 + 2
z)
(b)
Total amount that the three boys have
= 14 + 14 + 4
z + 14 + 2
z= 14 + 14 + 14 + 4
z + 2
z = $(42 + 6
z)
(c)
Amount that Luke has
= 14 + 2
z= 14 + 2 x 6
= 14 + 12
= $26
Answer(s): (a) $(14 + 2
z) or $(2
z + 14); (b) $(42 + 6
z) or $(6
z + 42); (c) $26
