Consider two air$-$conditioning systems with the cash flow estimates as given below. Use AW analysis to determine the sensitivity of the

economic decision to MARR values of $4\%,6\%,$ and $8\%$ per year.

The annual worth of air$-$conditioning system $1$ when the MARR is $4\%$ is $

The annual worth of air$-$conditioning system $2$ when the MARR is $4\%$ is $

The annual worth of air$-$conditioning system $1$ when the MARR is $6\%$ is $

The annual worth of air$-$conditioning system $2$ when the MARR is $6\%$ is $

The annual worth of air$-$conditioning system $1$ when the MARR is $8\%$ is $

The annual worth of air$-$conditioning system $2$ when the MARR is $8\%$ is $
