The weekly demand and cost functions for a product are
p= 1.89 - 0.0083x and c= 21+ 0.65x
write the profit function for this product.
find the marginal cost of the function.
C= 475 + 5.25x^2/3
find the marginal revenue function.
R= x(5+ 10/ sqrt(x)
Find the marginal profit function.
P= 1/15x^3 + 4000x^2 - 120x - 144,000
(a) Total Revenue = Px = 1.89x - 0.0083x^2
Total Profit = Total Revenue ...
