You have plans to attend 3 times this summer. Which option is best?
You think you will visit probably about 8 times this summer. Which option is best?
You have budgeted $150 for visiting the park this summer. Which option is best?
How many visits would be approximately the break even point where both options would cost about the same?

Answer 1

To determine which option is best in each scenario, we can calculate the total cost for both options based on the number of visits:

1. Single Visit Cost: $28 per visit.
2. Monthly Membership Cost: $90 + $15 per visit after purchasing the membership.

Let's define the total cost expressions for both options:

• Cost for single visits: \( C_{\text{single}} = 28 \times n \)
• Cost for membership visits: \( C_{\text{membership}} = 90 + 15 \times n \)

Where \( n \) is the number of visits.

Now let's evaluate each scenario:

1. You have plans to attend 3 times this summer:

   • Single cost: \( C_{\text{single}} = 28 \times 3 = 84 \)
   • Membership cost: \( C_{\text{membership}} = 90 + 15 \times 3 = 90 + 45 = 135 \)

   Best option: Single visits ($84)

2. You think you will visit probably about 8 times this summer:

   • Single cost: \( C_{\text{single}} = 28 \times 8 = 224 \)
   • Membership cost: \( C_{\text{membership}} = 90 + 15 \times 8 = 90 + 120 = 210 \)

   Best option: Membership ($210)

3. You have budgeted $150 for visiting the park this summer:

   • Single cost: \( C_{\text{single}} = 28 \times 5 = 140 \)
   • Membership cost: \( C_{\text{membership}} = 90 + 15 \times 4 = 90 + 60 = 150 \)

   Best option: Membership ($150)

4. How many visits would be approximately the break-even point where both options would cost about the same? Set both cost expressions equal to each other:

   \[ 28n = 90 + 15n \]

   \[ 28n - 15n = 90 \]

   \[ 13n = 90 \]

   \[ n = \frac{90}{13} \approx 6.92 \]

   Break-even visits: Approximately 7 visits

So here are the consolidated answers:

• 3 visits: Best option is Single visits ($84)
• 8 visits: Best option is Membership ($210)
• Budget of $150: Best option is Membership ($150)
• Break-even point: Approximately 7 visits
