Our client is the owner of a gas station between towns A and B – 10 miles to each town. He is wondering if it would make sense to add a convenience store to the gas station.
Clarifying Information
- There are no other gas stations in town A or B
- Gas is 75% of revenue (10% profit margin) and the gas station also offers car washes (25% of revenue, 20% profit margin)
- Criteria for “making sense” – 1) making profit, 2) having a better chance to hold off new competitors enter the market, 3) diversifying income
- The gas stations current customers are residents of town A and B; there are no other customers
