A video game arcade offers a yearly membership with reduced rates for game play. A single membership costs $60 per year. Game tokens can be purchased by members at the reduced rate of $1.00 per 10 tokens.
Which statements represent the function of the yearly cost in dollars, y, based on x, the number of game tokens purchased for a member of the arcade? Check all that apply.
The slope of the function is $1.00.
The y-intercept of the function is $60.
The function can be represented by the equation y = x + 60.
The domain is all real numbers.
The range is {y| y ≥ 60}.
The answer is The y-intercept of the function is $60, The function can be represented by the equation y= 1/10x + 60, and The range is {y| y (don't have the sign on my device) 60}. So choices B, C, and E.
The members slope is flatter by half compared to the non-members slope. The graphs intersect at 600 tokens and $120. Until that point the cost for non-members is less than the cost for members. After 600 tokens the cost for members is less than the cost for non-members.
