The equivalent annual costs of each model are as follows:
                        Model A    Model B
Equivalent annual costs   $2,389.26  $3,008.47
Data and Calculations:
                       Model A    Model B
Costs of motorcycle        $8,200     $13,600
Expected years of usage    7 years     9 years
Annual maintenance costs   $760      $740
Cost of capital = 9%
Annuity factor            5.03295     5.99524
PV of annual maintenance  $3,825.04  $4,436.48
Total NPV of costs       $12,025.04  $18,036.48
Equivalent annual costs  $2,389.26  $3,008.47
             ($12,025.04/5.03295)  ($18,036.48/5.99524)
Thus, the equivalent annual costs of each model are the dividend of the Total NPV costs divided by the Annuity Factor.
