  2. B Rs. 1875
  3. C Rs. 4790
  4. D Rs. 3383.75
Verified Solution

Answer & Solution

Correct Answer

(C) Rs. 4790

Step-by-step Solution

Detailed explanation

\(TC = \int (56 + \frac{3}{2}x) dx = 56x + \frac{3}{4}x^2 + C\) Fixed cost: \(C = 115\) \(TC(x) = 56x + \frac{3}{4}x^2 + 115\) \(TC(50) = 56(50) + \frac{3}{4}(50)^2 + 115\) \(TC(50) = 2800 + 1875 + 115 = 4790\)
