An amusement park that you are excited to try is $28 per visit.

You have the option to purchase a monthly membership for $90 and then pay $15 for each visit.

Put responses in the correct input to answer the question.

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

To evaluate the best option for visiting the amusement park, we need to compare the costs of the single visit option to the monthly membership option based on the number of visits.

  1. For 3 visits:

    • Single visit cost: \( 3 \times 28 = 84 \)
    • Monthly membership cost: \( 90 + (15 \times 3) = 90 + 45 = 135 \)
    • Which option is best? Single visit option
  2. For 8 visits:

    • Single visit cost: \( 8 \times 28 = 224 \)
    • Monthly membership cost: \( 90 + (15 \times 8) = 90 + 120 = 210 \)
    • Which option is best? Monthly membership option
  3. For a budget of $150:

    • Single visit cost for maximum visits:
      • \( 150 \div 28 \approx 5.36 \), so 5 visits would cost \( 5 \times 28 = 140 \) (under budget).
    • Monthly membership cost: \( 90 + (15 \times 4) = 90 + 60 = 150 \) (exactly at budget).
    • Which option is best? Monthly membership option (because you can visit 5 times with the single visit and 4 times with membership, but all 4 visits can be made).
  4. For the break-even point:

    • Let \( x \) be the number of visits.
    • Cost of single visits: \( 28x \)
    • Cost of membership: \( 90 + 15x \)
    • Set the two expressions equal: \[ 28x = 90 + 15x \] \[ 28x - 15x = 90 \] \[ 13x = 90 \] \[ x = \frac{90}{13} \approx 6.92 \]
    • The break-even point is about 7 visits.

Therefore, the responses are:

  1. Which option is best for 3 visits? Single visit option
  2. Which option is best for 8 visits? Monthly membership option
  3. Which option is best for a budget of $150? Monthly membership option
  4. How many visits would be approximately the break-even point? 7 visits
