Apex Company is currently producing and selling20,000 trees; the company has the excess capacity to handle this special order. The shopping mall has offered to pay$120 for each tree. An accountant at Apex Company provides an estimate of the unit product cost asfollows:
| Direct materials | 
$50.00 | 
| Direct labor (variable) | 
$3.50 | 
| Variable manufacturing overhead | 
$1.00 | 
| Fixed manufacturing overhead | 
$4.00 | 
| Total unit cost | 
$14.50 |
