Answer:
Results are below.
Explanation:
Giving the following information:
Month Number of Cavities Filled Total Cost
January 300 $5,100
February 375 5,300
March 625 6,350
April 400 5,200
May 650 6,300
June 600 6,300
July 350 5,000
August 675 6,300
September 550 6,000
<u>To calculate the fixed and variable cost under the high-low method, we need to use the following formulas:</u>
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (6,350 - 5,000) / (675 - 300)
Variable cost per unit= $3.6
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 6,350 - (3.6*675)
Fixed costs= $3,920
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 5,000 - (3.6*300)
Fixed costs= $3,920
<u>Now, for 700 units:</u>
Total cost= 3,920 + 3.6*700
Total cost= $6,440
