$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.
