I tried completing this problem with a group of 5 people last night, but none of us managed to figure it out. If someone here wants to take a stab at it, feel free and let me know what you did.

Thanks in advance!

The demand for a product is given as D(x) = 45 - 3x^2 and the supply is given as S(x) = 1/4x^3 + 3x - 2. Find the consumers and producers surpluses.
