The computation of the fixed cost and the variable cost per hour by using high low method is shown below:

Variable cost per hour = (High tutoring cost - low tutoring cost) ÷ (High service hours - low service hours)

= ($125,000 - $55,000) ÷ (4,300 hours - 1,500hours)

= $70,000 ÷ 2,800 hours

= $25

Now the fixed cost equal to

= High tutoring cost - (High service hours × Variable cost per hour)

= $125,000 - (4,300 hours × $25)

= $125,000 - $107,500

= $17,500
