The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)
As for number of variables, that depends on the aim of the study. More likely than not, I suspect the name of each person involved is irrelevant, which leaves 7 variables. (count the columns, excluding the first)
Answer:
$12
Step-by-step explanation:
If we stuck with the price of $8, then we end with an income of $2400
Increasing it by $1 will decrease attendance by 20
8 x 300 = 2400
9 x 280 = 2520
10 x 260 = 2600
11 x 240 = 2640
12 x 220 = 2640
13 x 200 = 2600
We're starting to go down, so let's stop there
The ticket price of $11 or $12 appears to give the most income
I would stick with $12 since your still getting more money from one ticket
