- August 4, 2023 at 1:03 am #689360Dear John, Please be kind enough to elaborate the answer for the following question; The following observations of output and cost have been made: Output Cost 
 8,000 Units $ 39,400
 20,000 Units $ 68,000It is known that at output levels above 15 000 units, variable cost per unit 
 drops by $1 per unit for all subsequent units produced.What is the variable 
 cost for each unit of output above 15 000 units?a. $1.80 
 ??
 b. $0.97
 c. $2.80
 d. $3.40August 4, 2023 at 10:00 am #689374For output of 20,000 units, the variable cost for 5,000 of them (the excess over 15,000) is $1 less than the ‘normal’ variable cost per unit. Therefore if the cost per unit hadn’t fallen, the total cost for 20,000 units would be $5,000 higher and be $73,000. If you then use the normal high low arithmetic with a cost of $73,000 for output of 20,000 units then you get a variable cost of $2.80 per unit. 
 This is what the variable cost is when ignoring the fall of $1. However the cost for each unit above 15,000 is $1 lower and is therefore $1.80.August 4, 2023 at 11:07 pm #689390Thank you very much for the Distinct explanation. I understand it completely now!
