Sean has $14. Reggie has $4
f more than Sean. Mark has $2
f less than Reggie.
- Find the amount of money that Mark has in terms of f.
- Find the total amount of money that the three boys have in terms of f.
- If f = 5, how much does Mark have?
(a)
Amount that Sean has = $14
Amount that Reggie has = $(14 + 4
f)
Amount that Mark has
= 14 + 4
f - 2
f = $(14 + 2
f)
(b)
Total amount that the three boys have
= 14 + 14 + 4
f + 14 + 2
f= 14 + 14 + 14 + 4
f + 2
f = $(42 + 6
f)
(c)
Amount that Mark has
= 14 + 2
f= 14 + 2 x 5
= 14 + 10
= $24
Answer(s): (a) $(14 + 2
f) or $(2
f + 14); (b) $(42 + 6
f) or $(6
f + 42); (c) $24
