Bryan has $10. Charlie has $5
p more than Bryan. Ethan has $2
p less than Charlie.
- Find the amount of money that Ethan has in terms of p.
- Find the total amount of money that the three boys have in terms of p.
- If p = 6, how much does Ethan have?
(a)
Amount that Bryan has = $10
Amount that Charlie has = $(10 + 5
p)
Amount that Ethan has
= 10 + 5
p - 2
p = $(10 + 3
p)
(b)
Total amount that the three boys have
= 10 + 10 + 5
p + 10 + 3
p= 10 + 10 + 10 + 5
p + 3
p = $(30 + 8
p)
(c)
Amount that Ethan has
= 10 + 3
p= 10 + 3 x 6
= 10 + 18
= $28
Answer(s): (a) $(10 + 3
p) or $(3
p + 10); (b) $(30 + 8
p) or $(8
p + 30); (c) $28
