Answer:
Total cost= $105,000
Step-by-step explanation:
Because the 15,000 units are in the relevant range, the fixed costs remain constant. Now, we need to calculate the total cost of 15,000 units:
Direct material= 15,000*2.5= 37,500
Direct labor= 15,000*0.75= 11,250
Variable overhead= 15,000*1.25= 18,750
Variable selling and administrative= 15,000*1.5= 22,500
Total variable cost= $90,000
Total fixed costs= $15,000
Total cost= $105,000
