Part 1 :
As per high low method, Variable cost per unit =
(Highest Activity Cost - Lowest Activity Cost) / (Highest Activity Units - Lowest Activity Units)
Highest Activity Level = Month 3 (because highest number of units are produced in month 3)
Highest Activity Cost = $54,000
Highest Activity Units = 12,500 Units
Lowest Activity Level = Month 7 (because lowest number of units are produced in month 7)
Lowest Activity Cost = $22,000
Lowest Activity Units = 4,500 units
Variable cost per unit = (Highest Activity Cost - Lowest Activity Cost) / (Highest Activity Units - Lowest Activity Units)
= ($54,000 - $22,000) / (12,500 - 4,500)
= $32,000 / 8,000
= $4 / unit
Total Processing Cost in month 3 = Fixed Cost per month + (Variable cost per unit * Number of Units produced in month 3)
$54,000 = Fixed Cost per month + ( $4 * 12,500)
$54,000 = Fixed Cost per month + $50,000
Fixed Cost per month = $54,000 - $50,000
= $4,000
NOTE : We can calculate the fixed cost by using the processing cost of month 7 (lowest activity level) as well.
Total Processing Cost in month 7 = Fixed Cost per month + (Variable cost per unit * Number of Units produced in month 7)
$22,000 = Fixed Cost per month + ( $4 * 4,500)
$22,000 = Fixed Cost per month + $18,000
Fixed Cost per month = $22,000 - $18,000
= $4,000
y = a + bx
In the above equation : y is the total cost , a is the fixed cost per month , b is the variable cost per unit and x is the number of units of the activity.
In Highest Activity Level : y = $54,000 , a = $4,000 , b = $4/unit , x = 12,500 units
y = a + bx
y = $4,000 + ($4 * 12,500)
y = $4,000 + $50,000
y = $54,000
Hence , the equation is verified.
In Lowest Activity Level : y = $22,000 , a = $4,000 , b = $4/unit , x = 4,500 units
y = a + bx
y = $4,000 + ($4 * 4,500)
y = $4,000 + $18,000
y = $22,000
Hence , the equation is verified.
Part 2 :
Total processing cost when 22,000 units are produced (y) = a + bx
y = $4,000 + ($4 * 22,000)
y = $4,000 + $88,000
y = $92,000
Therefore, total processing cost when 22,000 units are produced = $92,000
