Hope this helps!!!!
Answer:
500
Step-by-step explanation:
It's a box with a square base, so let's say the width and length are x and the height is y.
The surface area of the box without the top is:
A = x² + 4xy
300 = x² + 4xy
The volume of the box is:
V = x²y
Solve for y in the first equation and substitute into the second:
y = (300 − x²) / 4x
V = x² (300 − x²) / 4x
V = x (300 − x²) / 4
V = 75x − ¼ x³
To optimize V, find dV/dx and set to 0:
dV/dx = 75 − ¾ x²
0 = 75 − ¾ x²
x = 10
So the volume of the box is:
V = 75x − ¼ x³
V = 500
The maximum volume is 500 cm³.

Answer:
X = 35
Step-by-step explanation:
- Subtract 6 from both sides.
2x+6−6=76−6
2x=70
÷
= 35
Mid point elasticity formula
[change in price] / [average price] ÷ [change in quantity] / [average quantity]
change in price = $6 - $4 = $2
average price = [$ 6 +$4] / $2 = 10/ 2 = 5
[change in price] / [average price] = 2/5
change in quantity = 1000 boxes - 600 boxes = 400 boxes
average quantity = [1000 boxes + 600 boxes] / 2 = 1600 boxes / 2 = 800
boxes
change in quantity / average quantity = 400/800 = 1/2
midpoint elasticity = 2/5 ÷ 1/2 = 4/5 = 0.8
0.8 < 1 => inelastic demand (the change is demand is less than proportional to the change in price)
