A video arcade charges an entrance fee, then charges a fee per game played. The entrance fee is $5, and each game costs an additional $1. Find the total cost for playing 0, 1, 2, or 3 games. Describe the total cost with an explicit equation.
  1. Use the description of the costs to find the total costs.
  2. Identify the independent and dependent quantities.
  3. Determine if there is a common difference or a common ratio between the dependent terms.
  4. Use the common difference to write an explicit equation.
  5. Evaluate the equation to verify that it is correct.
