Question

The total cost C(x) associated with provision of free mid-day meals to x students of a school in primary classes is given by C(x) = 0.005x³-002x² +30x+50. If the marginal cost is given by rate of dC change of total cost, then write the dx marginal cost of food for 300 students. What value is shown here?


Plz plz plz helpme

Do not tell wrong answer plz​

Answer 1

Answer:

Given, C(x) = 0.005x³ -0.02x² + 30x + 50

On differentiating both sides w.r.t. x, we get dC dx = 0.005(3x²) -0.02(2x) + 30 = 0.015x² -0.04x + 30

On putting x = 300, we get dC dx 0.015(300)2 -0.04(300) + 30

= 1350-12 +30=1368 (1/2)

By providing free mid-day meals to students of primary classes, care and concern is shown towards their health and nutritional status. (1/2)
