Answer:
3 GB over: $80 x GB over: $35+$15x
Step-by-step explanation:
First, 3 GB over is 3 times 15 plus 35, which equals 80. x GB over is x times 15 plus 35, hence the answer. Hope this helps!
The dish illustrates operations on a parabola.
The depth of the parabolish dish is 160 feet.
The bowl is said to be a parabola.
So, we have:

Where:


From the question, the diameter is 160 feet.
So, the radius (r) is:

So, the coordinate of the depth of the parabola would be:


Substitute these values in 
So, we have:


Divide both sides by 160

Rewrite as:

Hence, the depth of the parabolish dish is 160 feet.
