Showing the table of x's and y's should be present in order to get the range of the function. The range can be acquired through the y values.
The sum of the interior angles of a polygon with
sides is

Since a pentagon has 5 sides, the sum of its interior angles is

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures
degrees.
Since this question is asking for the unit rate of the cost per yard of fabric, think of this as a ratio and proportions question where 2.6:8.94 = 1:x (represents the cost per yard).
To solve, cross multiply to get 2.6x=8.94
Then, solve for x and you get about $3.44 per yard
