Question

Conor buys 75 tokens for games at the arcade. the price to play each game is 3 tokens. if conor has already played x games, which expression is equivalent to the number of tokens that remain?

Answer 1

y = 75 - 3x

Explanation:

Let the number of token left = y

total number of token bought = 75

Number of games played by Conor = x

It is given for playing one game, the price = 3 token

Therefore for playing x games, the price is = 3x

Therefore, the number of tokens left with Conor is given by

y = 75 - 3x

Thus, the expression that is equivalent to the number of remaining tokens is

y = 75 - 3x

Answer 2

For this case we have the following variables:
x: number of games
y: number of remaining tokens
The expression that models the problem is given by:
y = -3x + 75
Answer:
the number of tokens that remain is:
y = -3x + 75
