Question

Please help so lost on how to do this??????

Answer 1

Okay first,     breathe!  It's gonna be okay

So this is simply a linear function/equation/system. 
How you do this is by plugging in the numbers provided in the left column of the table (2, 4, 6, 8) into the equation provided, (f=19s+9).

For example, for the top one, 2, what they did was substitute 2 for s which looks like this   -->   19(2)         and the whole equation   -->   f= 19(2) +9

sooo.. if you were to solve you would get 47 (PEMDAS)
You can then do this for the remaining ss.

But if you're just looking for the answers then they are:

4: 85
6: 123
 

Hope you do good :)

Answer 2

First thing I can multiply in the answer I get from all the flying you're going to add that number and you'll get your answer
