Answer:
The variable factory utility cost per case bottled is closest to $0.13
Explanation:
High low method separates the fixed cost and variable cost using net of Highest activity level and Lowest activity level and net of their relevant costs.
According to High low method
Variable cost per unit = ( Highest activity cost - Lowest activity cost ) / ( Highest Activity - Lowest activity )
Variable cost per unit = ( $3,766 - $3,686 ) / ( 1,900 cases - 1,300 cases )
Variable cost per unit = $80 / 600 cases
Variable cost per unit = $0.13333333333
Variable cost per unit = $0.13 ( rounded off to 2 decimal places )
