Answer:
b. $0.40 per unit and $8,000
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 = ( $120,000 - $74,000 ) / ( 280,000 - 165,000 )
Variable cost per unit = $46,000 / 115,000
Variable cost per unit = $0.4
Fixed operating cost = Total cost - Total Variable cost = $120,000 - ( 280,000 x $0.4 ) = $8,000
