At the high level of activity in November, 12000 machine hours were run and power costs were $20000. In April, a month of low activity, 4000 machine hours were run and power costs amounted to $11000. Using the high-low method, the estimated fixed cost element of power costs is

$6,500

Explanation:

For computing the estimated fixed cost, we have to determine the variable cost per hour which is shown below:

Variable cost per hour = (High power cost - low power cost) ÷ (High machine hours - low machine hours)

= ($20,000 - $11,000) ÷ (12,000 hours - 4,000 hours)

= $9,000 ÷ 8,000 hours

= $1.125

Now the fixed cost equal to

= High power cost - (High machine hours × Variable cost per hour)

= $20,000 - (12,000 hours × $1.125)

= $20,000 - $13,500

= $6,500

they work in some type of way
