PSAT Math Multiple-Choice Question 322: Answer and Explanation

Question: 322

The figure above shows the cost of going to a certain carnival. What does the y-intercept most likely represent?

• A. A flat entrance fee
• B. The cost of riding 8 rides
• C. The cost of attending the carnival 8 times
• D. The total cost of attending the carnival and riding 1 ride

Correct Answer: A

Explanation:

A

Difficulty: Easy

Category: Linear Graphs

Getting to the Answer: Read the axis labels carefully. The y-intercept is the point at which x = 0, which means the number of rides is 0. The y-intercept is (0, 8). This means the cost is $8 before riding any rides, and therefore 8 most likely represents a flat entrance fee, (A).
