Answer:
Total cost formula= 6,388 + 6.76x
Explanation:
Giving the following information:
Month Number of Lab test performed Test Laboratory overhead cost
January 2,800 $21,500
February 2,600 $22,700
March 3,100 $27,900
April 3,550 $31,400
May 3,700 $28,500
June 1,200 $19,500
July 1,400 $14,500
<u>To calculate the variable and fixed cost, we need to use the following formula:</u>
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (31,400 - 14,500) / (3,700 - 1,200)
Variable cost per unit= $6.76
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 31,400 - (6.76*3,700)
Fixed costs= $6,388
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 14,500 - (6.76*1,200)
Fixed costs= $6,388
Total cost formula= 6,388 + 6.76x
