Should Open Seas go ahead with the purchase? d. How far off could OpenSeas's cost of capital estimate be before your purchase decision would change? a. Prepare an NPV profile of the purchase. To plot the NPV profile, we compute the NPV of the project for various discount rates and plot the curve. The NPV for a discount rate of 2.0% is $ million. (Round to one decimal place.)
