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.
