To construct NPV profiles for Projects A and B, we first need to calculate the Net Present Value (NPV) for each project at various discount rates. To calculate NPV, we use the following formula:

$NPV = \sum \frac{C_t}{(1 + r)^t}$ Where:

• $C_t$ = Cash flow at time $t$,
• $r$ = Discount rate,
• $t$ = Time period.

However, in order to provide the specific NPV values, I need details about the cash flows (C_t) for each project. Could you provide the cash flow information for both Project A and Project B over the relevant periods? Once I have those, I can calculate the NPV at the given discount rates and complete the table for you.
