The equation for the total number of cases is ...
x + y = 20
The equation for the total cost of the cases is ...
20x +30y = 450
_____
<em>Additional comment</em>
The solution to these equations is (x, y) = (15, 5).
Let the side of the cube=a
So the volume will be=V=a³
Then surface area of the cube will be=6a²=
= 
The above expression showing surface area as a function of Volume. (Answer)

Answer:
4 amperes
Step-by-step explanation:
I graphed the function on the graph below to find the maximum value of c.
Difference quotient = [f(x+h) - f(x)]/h
[-5(x+h) -3 - (-5x -3)]/h
[-5x -5h -3 + 5x +3]/h
[-5h]/h
-5
