Liam has $9. Valen has $5
b more than Liam. Perry has $2

- Find the amount of money that Perry has in terms of b.
- Find the total amount of money that the three boys have in terms of b.
- If b = 7, how much does Perry have?
(a)
Amount that Liam has = $9
Amount that Valen has = $(9 + 5
b)
Amount that Perry has
= 9 + 5
b - 2
b = $(9 + 3
b)
(b)
Total amount that the three boys have
= 9 + 9 + 5
b + 9 + 3
b= 9 + 9 + 9 + 5
b + 3
b = $(27 + 8
b)
(c)
Amount that Perry has
= 9 + 3
b= 9 + 3 x 7
= 9 + 21
= $30
Answer(s): (a) $(9 + 3
b) or $(3
b + 9); (b) $(27 + 8
