Given:

Sol:
Area of picture is:

If the cost $10 per square inch then price of 15 square inch is:

If the quadruple of dimension that mean:

So area is:

So price is:
I believe it's y'(0)=-3
I was only able to simplify the equation.
Hope this helps
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
