You recently went to work for Harper's Motor Company, a supplier of auto repair parts used in the after$-$market with products from Fiat, General Motors, Ford and Honda as well as other automakers. The CFO has provided you with the cash flows for two proposed projects. Project A involves adding a new item to the firm's ignition system line; it would take some time to build up the market for this product so that cash inflows would increase over time. Project B involves an add$-$on to an existing line, and its cash flows would decrease over time. Both projects have $3-$year lives because Harper's is planning to introduce entirely new models after $3$ years.

Here are the projects' after$-$tax cash flows $($in thousands of dollars$).$
