Answer:
The expression [tex]18-3x[/tex] describe the number of tokens Nadeen has left.
Step-by-step explanation:
Consider the provided information
Nadeen is at an arcade. She started with 18 tokens. Each game costs 3 tokens.
The cost of each game is 3 tokens
Suppose x is the number of games played by Nadeen
Thus, the cost of x games is 3x tokens
it is given that Nadeen started with 18 tokens.
So, token left = [tex]18-3x[/tex]
Therefore, the expressions [tex]18-3x[/tex] can be used to describe the number of tokens Nadeen has left.
