Answer:

Explanation:
Given : James is playing his favorite game at the arcade.
After playing the game 3 times, he has 8 tokens remaining.
Initial number of tokens he had = 20
Also the game costs the same number of tokens each time.
Let x be the cost of each game .
Then according to the above information we have,

[Subtract 8 from both sides]
x= 4 [Divide 3 from both sides]
i.e. the cost of each game = 4 tokens
Let g be the number of games he plays.
Then , the function of number t of tokens James has will be :
t= Initial tokens - (Tokens required for each game)(g)
