Brad works at an ice skating rink. Yesterday, the rink had 8 skating sessions that were each an hour and a half long, with 15 minutes in between for resurfacing the ice. This table shows the number of people who skated during each session.

The admission cost is $6.00 for children ages 5–18 and $9.00 for adults. Children under 5 skate for free. Skate rental is $3.00. A small percentage of skaters bring their own skates. Which graph could accurately show the revenue collected from the skaters at the 9:00 a.m. session?

To determine which graph could accurately show the revenue collected from skaters at the 9:00 a.m. session, we will need to consider several factors based on the information provided about the rink's pricing and the number of people skated.

  1. Identify the number of skaters: You need to refer to the table that shows the number of skaters who participated in the 9:00 a.m. session.

  2. Classify the skaters: Separate the skaters into categories (children ages 5–18, adults, and children under 5) if possible, to analyze their respective admission fees.

  3. Calculate total admission revenue:

    • For children 5–18, the revenue would be calculated as: \[ \text{Number of Children} \times 6.00 \]
    • For adults, the revenue would be: \[ \text{Number of Adults} \times 9.00 \]
    • Children under 5 skate for free, so they do not contribute to revenue.
  4. Calculate total skate rental revenue: If you have the data on how many skaters rented skates and how many brought their own, calculate the revenue from skate rentals. \[ \text{Number of Rentals} \times 3.00 \]

  5. Add total revenues: Total revenue is the sum of the admission revenue and the skate rental revenue.

  6. Graph Representation: Look for a graph that correctly presents the total revenue calculated in the step above. It could be represented as a bar graph, pie chart, or line graph, depending on how the options are structured.

After analyzing the numbers and the revenue calculations, select the graph that visually represents your findings accurately. Without the specific table of skaters from the 9:00 a.m. session, I cannot specify which graph it is, but ensure the graph you choose displays the calculated total revenue accurately based on your earlier calculations.
