Michael has $12. Bobby has $5
p more than Michael. Ian has $2
p less than Bobby.
- Find the amount of money that Ian has in terms of p.
- Find the total amount of money that the three boys have in terms of p.
- If p = 5, how much does Ian have?
(a)
Amount that Michael has = $12
Amount that Bobby has = $(12 + 5
p)
Amount that Ian has
= 12 + 5
p - 2
p = $(12 + 3
p)
(b)
Total amount that the three boys have
= 12 + 12 + 5
p + 12 + 3
p= 12 + 12 + 12 + 5
p + 3
p = $(36 + 8
p)
(c)
Amount that Ian has
= 12 + 3
p= 12 + 3 x 5
= 12 + 15
= $27
Answer(s): (a) $(12 + 3
p) or $(3
p + 12); (b) $(36 + 8
p) or $(8
p + 36); (c) $27
