Question $1$:

Consider the net cash flows $($NCF$)$ and salvage values $($SV$)$ shown below.

The interest rate is $10\%$ per year. Assume the alternatives can be

indefinitely renewed with the same cash flows and salvage values. Specify

the planning horizon and complete set of cash flows for each alternative

using each of the following:

Alternative $1$ Alternative $2$

a$.$ Least common multiple of lives

b$.$ Shortest life among alternatives

please don't solve using excel solve by hand. $$ If a problem has uniform series and$/$or gradients, solve using corresponding A$,$ G$,$ g rules. For such problems, DO NOT solve by simply getting the P or F for each year separately.
