Ivan has $11. Mark has $5
f more than Ivan. Ahmad has $2
f less than Mark.
- Find the amount of money that Ahmad 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 Ahmad have?
(a)
Amount that Ivan has = $11
Amount that Mark has = $(11 + 5
f)
Amount that Ahmad has
= 11 + 5
f - 2
f = $(11 + 3
f)
(b)
Total amount that the three boys have
= 11 + 11 + 5
f + 11 + 3
f= 11 + 11 + 11 + 5
f + 3
f = $(33 + 8
f)
(c)
Amount that Ahmad has
= 11 + 3
f= 11 + 3 x 5
= 11 + 15
= $26
Answer(s): (a) $(11 + 3
f) or $(3
f + 11); (b) $(33 + 8
f) or $(8
f + 33); (c) $26
