A group of friends wants to go to the amusement park. They have $214.50 to spend on parking and admission. Parking is $12, and tickets cost $33.75 per person, including tax. Which tape diagram could be used to represent the context if pp represents the number of people who can go to the amusement park?

1 answer

To represent the situation with a tape diagram, we need to break down the total expenses, which include parking and admission tickets based on the number of people attending.

Given:

  • Total budget: $214.50
  • Parking cost: $12
  • Admission ticket cost per person: $33.75
  • Let \( pp \) represent the number of people.

Steps to Set Up the Tape Diagram:

  1. Total Expenses: The total expenses consist of the parking cost plus the total cost of admission for all the people: \[ \text{Total cost} = \text{Parking} + \text{Admission for } pp \text{ people} \] This can be expressed as: \[ \text{Total cost} = 12 + 33.75 \times pp \]

  2. Budget Constraint: The total cost must not exceed the budget: \[ 12 + 33.75 \times pp \leq 214.50 \]

Tape Diagram Representation:

In the tape diagram, you can use the following representation:

  • One section for Parking: A segment labeled "Parking ($12)"
  • Multiple sections for Admission: A longer segment that is divided into \( pp \) equal parts, where each part is labeled $33.75 (Admission ticket for 1 person).
  1. Connecting the Total: The entire length of the tape would represent the total budget of $214.50 with a visual representation showing:
    • One segment of length representing $12 for parking.
    • \( pp \) segments of length $33.75 each for the admission costs.

In summary, a tape diagram could be structured as follows:

  • Total tape length representing $214.50
  • One segment (short) for Parking ($12)
  • \( pp \) segments (each of equal length) for Admission ($33.75 per person)

This visual will clearly show how the budget is allocated for parking and admission based on the number of people \( pp \).
