them are significant. Therefore‚ demand function can be written as Q = 2308.5 – 49.06*P + 0.07038*M + 0.033636*N 2) Demand function has coefficient of price as -49.06‚ meaning every increase of $1 in membership price causes demanded quantity to fall by about 49. Coefficient of average income is 0.07038‚ meaning a rise of $1000 in average income leads to an increase of about 70 in quantity demanded. Coefficient of population is 0.033636‚ meaning for every increase of 1000 in population‚

and calculate average and marginal cost to make production decisions.” Reference: Gregory Mankiw’s Principles of Microeconomics‚ 2nd edition‚ Chapter 13.

Marginal Costs and Benefits Marginal analysis is a technique used in microeconomics by which very small changes in specific variables are studied in terms of the effect on related variables and the system as a whole.
