Peter has $11. Valen has $4
z more than Peter. Fabian has $2
z less than Valen.
- Find the amount of money that Fabian has in terms of z.
- Find the total amount of money that the three boys have in terms of z.
- If z = 7, how much does Fabian have?
(a)
Amount that Peter has = $11
Amount that Valen has = $(11 + 4
z)
Amount that Fabian has
= 11 + 4
z - 2
z = $(11 + 2
z)
(b)
Total amount that the three boys have
= 11 + 11 + 4
z + 11 + 2
z= 11 + 11 + 11 + 4
z + 2
z = $(33 + 6
z)
(c)
Amount that Fabian has
= 11 + 2
z= 11 + 2 x 7
= 11 + 14
= $25
Answer(s): (a) $(11 + 2
z) or $(2
z + 11); (b) $(33 + 6
z) or $(6
z + 33); (c) $25
