Answer:
He should invest in oil rig as it gives profit of $9,632,000.
Explanation:
According to the scenario, computation of the given data are as follows:
Paid to engineer = $8,000
Invest in oil rig = $2,000,000
Rate of discount = 22%
So, Discount amount = $2,000,000 X 22% = = $440,000
Expected oil = 40,000 barrels per year
So, Total oil after 8 years = 40,000 × 8 = 320,000 barrels
Selling price = $35
So, total sales value = 320,000 × $35 = $11,200,000
Total profit = (Total sales + Discount amount) - (Total Investment + Paid to engineer)
= ( $11,200,000 + $440,000 ) - ( $2,000,000 + $8,000)
= $11,640,000 - $2,008,000
= $9,632,000
As this gives the profit of $9,632,000, so he should invest in oil rig.
