Neave has $10. Ben has $4
f more than Neave. Bobby has $2
f less than Ben.
- Find the amount of money that Bobby has in terms of f.
- Find the total amount of money that the three boys have in terms of f.
- If f = 7, how much does Bobby have?
(a)
Amount that Neave has = $10
Amount that Ben has = $(10 + 4
f)
Amount that Bobby has
= 10 + 4
f - 2
f = $(10 + 2
f)
(b)
Total amount that the three boys have
= 10 + 10 + 4
f + 10 + 2
f= 10 + 10 + 10 + 4
f + 2
f = $(30 + 6
f)
(c)
Amount that Bobby has
= 10 + 2
f= 10 + 2 x 7
= 10 + 14
= $24
Answer(s): (a) $(10 + 2
f) or $(2
f + 10); (b) $(30 + 6
f) or $(6
f + 30); (c) $24
