Answer:
Buy
Explanation:
First, we need to find out what is the cost incurred by the company in building the power station and after that, we will compare that cost with the selling price of the power from Tri-county G&T. the lower-priced option will be considered as best option.
Cost incurred by the company in building the power station = $10,000,000 + (150,000 x $35)
Cost incurred by the company in building the power station = $10,000,000 + $5,250,000
Cost incurred by the company in building the power station = $15,250,000
Selling price of the power from Tri-county G&T = 150,000 x $75
Selling price of the power from Tri-county G&T = 11,250,000
Decision: It would be a wise option for the company to buy it. From buying the power the company will save $4m.
