Answer:
The option d is correct.
Explanation:
The high low method shows the difference between the high and low cost of a particular thing. In the given question, the high cost is $3,600 and the low cost is $2,700 whereas the high machine hour is 18000 and low machine hour is 10,000.
Now, the formula for high low method is calculated. It is shown below:
High low method = (High cost - Low cost) ÷ (High machine hours - Low machine hours)
= ($3,600 - $2,700) ÷ (18000 - 10,000)
= 900 ÷ 8000
= 0.11
Thus, the option d is correct.
