Given the following Average cost function: 7.1 Determine the marginal cost function. c = 10 + 10q – 4q² + q³
7.2 Determine the marginal cost when q = 100. 7.3 Determine the average cost when q = 210. 7.4 If the production quantity is to be increased by 1 unit at a present production level of 210 units, determine by how much the total cost would increase.
