Answer:
L = 100
W = 60
Step-by-step explanation:
2L + 2W = 320
-2L + 2W = -80
4W = 240
W = 60
L - W = 40
L - 60 = 40
L = 100
The cost of the bottle alone costs $1.15, and the cork costs $0.05, you add them together and you get $1.20. That is how the bottle costs $1.20.
I'm believing that you have the measurements in the right order, lwh, the Volume would be 5,000. You'd take 40 x 25 x 2= 5,000.
The weight is 2.5 oz. You get this answer by taking the Volume, 5,000, and multiply it by 0.0005 and you get 2.5 ounces.
