Explanation:

                         1,000 units of output           5,000 units of output

                         direct materials                    direct materials

                         $5,000     $5.00                   $25,000      $5.00

                        utilities expense                    utilities expense

                         $1,000       $1.00                    $3,750        $0.75

                         rent expense                          rent expense

                         $4,000       $4.00                  $4,000        $0.80

Utilities expense is a mixed expense since it has a fixed amount + a variable amount, that is why average utilities expenses cost per unit decreases only a little as the number of units produced increase. For 1,000 units the utilities expense = $1,000, while as the units increase, the utilities expense increases to $3,750, but the average cost per unit decreases from $1 to$0.75.

Rent expense is a fixed cost, since it is equal to $4,000 no matter how many units are produced.
