Answer:

Step-by-step explanation:
We are given the following in the question:
Let the equation:

be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f

Temperature at 12000-foot level = 49 f

Solving the two equation, we get,

Thus, we can write the linear equation as:

Wherever the line hits on the horizontal line on a graph.

Hey There!
To find how many seats are needed to be added, you need to subtract 15,340 by 13,451. You need to find the difference between the seats you need and the seats you have. So...
15,340-13,451= 1,889
You need to add 1,889 more seats.
Hope This helped!
Godspeed,
