Perry has $13. Reggie has $5
n more than Perry. Oliver has $2
n less than Reggie.
- Find the amount of money that Oliver has in terms of n.
- Find the total amount of money that the three boys have in terms of n.
- If n = 5, how much does Oliver have?
(a)
Amount that Perry has = $13
Amount that Reggie has = $(13 + 5
n)
Amount that Oliver has
= 13 + 5
n - 2
n = $(13 + 3
n)
(b)
Total amount that the three boys have
= 13 + 13 + 5
n + 13 + 3
n= 13 + 13 + 13 + 5
n + 3
n = $(39 + 8
n)
(c)
Amount that Oliver has
= 13 + 3
n= 13 + 3 x 5
= 13 + 15
= $28
Answer(s): (a) $(13 + 3
n) or $(3
n + 13); (b) $(39 + 8
n) or $(8
n + 39); (c) $28
