Ivan has $9. Pierre has $4
p more than Ivan. Harry has $2
p less than Pierre.
- Find the amount of money that Harry 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 Harry have?
(a)
Amount that Ivan has = $9
Amount that Pierre has = $(9 + 4
p)
Amount that Harry has
= 9 + 4
p - 2
p = $(9 + 2
p)
(b)
Total amount that the three boys have
= 9 + 9 + 4
p + 9 + 2
p= 9 + 9 + 9 + 4
p + 2
p = $(27 + 6
p)
(c)
Amount that Harry has
= 9 + 2
p= 9 + 2 x 5
= 9 + 10
= $19
Answer(s): (a) $(9 + 2
p) or $(2
p + 9); (b) $(27 + 6
p) or $(6
p + 27); (c) $19
