Assume a profitable economic well produces an average income of $23 million, while the average cost of a dry hole is $1.2 millio
bezimeni [28]

The most appropriate choice for revenue and profit will be given by-

Profit expected from a 100-well drilling program = $146.2

What is revenue and profit?

Total income generated by sale of goods and service is called revenue.

If p is the cost of producing one unit of a commodity and q is the number of units of the commodity, then the product of p and q gives the revenue.

If the revenue obtained by selling a commodity is more than the cost, difference between revenue and cost gives the profit.

Here,

Number of economic wells = 11

An economic well produces an average income of $23

Revenue obtained = $$(23 \times 11)

Number of dry wells = 100 - 11

                                  = 89

Average cost of a dry hole is $1.2 million

Cost of 89 dry holes = $$(89 \times 1.2)

                                   = $106.8

Profit = Revenue - cost

         = $(253-106.8)

         = $146.2

Profit  expected from a 100-well drilling program = $146.2
