Answer:
Options (a) and (c)
Step-by-step explanation:
There are so many inequalities graphed in the picture attached.
Common area (Triangle shown in the center) of the shaded regions will be the solution of the system of inequalities.
And points lying in this common region will be the solutions.
Points lying in this region are (0, -1) and (0, 0).
Therefore, Options (a) and (c) are the solutions.
We can simplfiy to be 
.
We know that
is 10 and
is i, so the answer is 10i, or D.
The maximum revenue is $700 which is at 16 combo A and 12 combo B.
<h3>
Inequality</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let x represent the number of combo A and y represent the number of combo B, hence:
10x + 20y ≤ 400 (1)
Also:
x + y ≤ 28 (2)
The solution is at (16,12). Hence:
Revenue = 21.25 * 16 + 30 * 12 = $700
The maximum revenue is $700 which is at 16 combo A and 12 combo B.

For the mean you add them all up and divide by the ammount of numbers you added. So it would be 118
