Question

climb time is a different rock - climbing gym. it also costs $30 per month, but new members pay a one - time equipment fee when they sign up.
what does the point (0, 20) tell you?
the cost of the first month is $20.
the one - time equipment fee is $20.
the gym costs $20 per month.
the first 20 months are free.
(chart: x - axis: number of months, y - axis: total cost ($); two lines: climb time (starts at (0,20)) and rock zone (y = 30x, starts at (0,0)) )

Explanation:

In the context of the graph, the x - axis represents the number of months and the y - axis represents the total cost. The point \((0,20)\) means when the number of months \(x = 0\) (i.e., at the time of signing up, before any months of membership have passed), the total cost \(y=20\) dollars. Since the gym has a monthly cost of \$30 and a one - time equipment fee, this \$20 at \(x = 0\) (no months of membership) must be the one - time equipment fee. The first option is wrong because the monthly cost is \$30, so the first month's cost would be more than \$20. The third option is wrong as the monthly cost is given as \$30. The fourth option is wrong as the cost at LXI3 is \$20, not free for 20 months.

Answer:

The one - time equipment fee is \$20.
