L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.

Answer:
Bottle containing cranberry juice has a greater percent of water.
Step-by-step explanation:
A 60 ounce bottle of grape juice contains 33 ounces of water.
So the percentage of water in the bottle = 
= 
= 55%
Similarly 50 ounces bottle of cranberry juice contains 30 ounces of water.
So the percentage of water in the bottle = 
= 
= 60%
Therefore, bottle containing cranberry juice has a greater percent of water.
