a) Total revenue is R = 4x
Total cost isC = 50 + 1.3x + 0.001x^2
Profit is given byP = R - C = 4x - (50 + 1.3x + 0.001x^2)
P = 4x - 50 - 1.3x - 0.001x^2
P = 2.7x - 50 - 0.001x^2
b) To find the value of x that maximizes profit, take the first derivative and set it equal to zero:
\frac{dP}{dx} = 2.7 - 0.002x = 0
Solve for:
2.7 = 0.002x
x = \frac{2.7}{0.002}
x = 1350
c) Substitute back into the profit function:
P = 2.7(1350) - 50 - 0.001(1350)^2
P = 3645 - 50 - 1822.5
P = 1250
So, the maximum utility is 1250 and the production volume that maximizes it is 1350 units.
Total cost is
