Letisha is running a catering service. She wants to expand her operations and open a restaurant. This would involve a purchase of a building and equipment necessary for running her intended business; the total present cost of this economic investment would be $220,000. Letisha is aware of interest rates and she wants to maximize her profit. She calculates that this new business venture would yield a payoff of $300,000 in 5 years. Given the interest rate of 5% and assuming no other costs and benefits or risks are involved, Letisha calculates that the present value of the future benefit is [ Select ] ["$39,506", "$172,375", "$220,000", "$235,058", "$300,000", "$382,884."] .Since the present cost is [ Select ] ["lower", "higher"] than the present value of the future benefit, Letisha decides to [ Select ] ["proceed with her economic investment and open the restaurant.", "forgo the economic investment and keep her money in a savings account with the same interest rate."] . If the interest rate were [ Select ] ["2% lower (i.e. at 3%)", "1% lower (i.e. at 4%)", "1% higher (i.e. at 6%)", "2% higher (i.e. at 7%)"] , she would forgo this economic investment.
