Hello.
Question 4:
-2.34n = -12.168
Divide both sides by -2.34;
n = 5.2 is your answer to #4 (Answer choice "C.)"
For Question 5:
-8c = 56
Divide both sides by -8 to solve for c;
c = -7 (remember your signs!) is your answer for #5 (Answer choice "C.)"
= -2; To solve for this, we need to multiply both sides by -12.168 to isolate and solve for our variable.
= -2; Multiply by -12.168
n = 24.336 (A negative multiplied by a negative results in a positive product.);
Your answer for #3 is n = 24.336 (Answer choice "B.)")
I hope this helps!

Answer:
$ 327.08
Step-by-step explanation:
Let w be the width ( in meters ) of the container,
⇒ Length of the container = 2w,
If h be the height of the container,
So, the volume of the container = length × width × height
= 2w × w × h
= 2w² h
According to the question,
Now, the area of the base = length × width
Area of sides = 2 × length × height + 2 × width × height
Since, material for the base costs $20 per square meter and material for the sides costs $12 per square meter,
Hence, total cost,
Differentiating with respect to w,
Again differentiating with respect to w,
For maxima or minima,
C'(w) = 0
For w = 1.651, C''(w) = positive,
Thus, cost is minimum for width 1.651 meters,
And, the minimum cost = C(1.651) =
