They will purchase 3 tickets for seats in row 12.
What is the average (arithmetic mean) ticket price, in dollars, for the 10 tickets? (Disregard the $ sign when gridding your answer.
The correct answer is: 20
Purchase of 3 tickets in row 1 = 3 × 25
Purchase of 2 tickets from row 3 & 4 = 4 × 20
Purchase of 3 tickets from row 12 = 3 × 15
Average = 
= 20.

A researcher is investigating the relationship between the price of a four-pack of AA batteries at a convenience store and the number of competitors the store has. She defines a store’s competitor as another similar store within a 1-mile radius of the store she selects. She selects 32 convenience stores across a state at random, and for each store, she records the number of its competitors and its price for a four-pack of AA batteries. The results are shown, along with the line of best fit, in the scatterplot below.
The line of best fit passes through the point (18, -0.12). Which of the following can be concluded from this?

Another convenience store in the same state sells a four-pack of AA batteries for $4.89. If the store’s price is more than that predicted by the line of best fit, what is the least number of competitors the store could have?
