Answer:

Step-by-step explanation:
Given

Write a recursive expression

When n = 1


When n = 2

can be rewritten as

Substitute 3 for f(1)

Express 1 as 2 - 1
----- (1)
When n = 3

can be rewritten as

Substitute 8 for f(2)

Express 2 as 3 - 1
------ (2)
Write out (1) and (2)


Replace 2 and 3 with n in both cases; This gives

Hence;
The recursive is 
Let x represent the amount of games played.
When x is used, it need to be multiplied by the price ($35).
x(35) = cost in $
