ExampleExample

Company produces crude oil from a field where the basis of decision is the number of barrels produced. Two methods for production are:

automated tank battery manually operated tank battery

ExampleExample

Small firm sells garden chemicals. x = number of tons sold per yearSP(x) = selling price per ton (to sell x tons)

= $(800 - 0.8x)TR(x) = total revenue at x tons

= $(800 - 0.8x) xTC(x) = total production cost for x tons

= $(8,000 + 400x)

ExampleExample

TP(x) = total profit at x tons = TR(x) - TX(x) = (800x - 0.8x2) - (8,000 + 400x) = -0.8x2 + 400x - 8,000
