PSAT Math Multiple-Choice Question 655: Answer and Explanation

Question: 655

Assuming that the trend represented in the graph continues over the next decade (which is not portrayed in the graph), the average price of a football ticket in the year 2014 would most likely be:

• A. $41
• B. $47
• C. $56
• D. $62

Correct Answer: B

Explanation:

(B) As you can see from the graph, the trend is a slight decrease in slope each year (while remaining positive). Thus, we would expect ticket prices to rise again but only slightly. You can use the slope from the previous year to get an idea of an approximate increase in the next few years. It looks like from 2009 to 2010, the price increased from $42 to $43, so the price increased by $1. If it continues to increase about $1 for the next 4 years until 2014, the price will go up a total of $4, from $43 to $47, which is choice (B).
