The checkout operator costs $28,000 per year (assume this is also at the end of each year beginning with year 1), and this amount is expected to increase at 5% annually. If the supermarket's cost of capital is 10%, which alternative should be selected. Assume all annual cashflows occur at the end of each year Fill in your answer here Help
