Answer and Explanation:
The computation of the fixed cost and the variable cost of electricity per occupancy-day by using high low method is shown below:
The Variable cost of electricity per occupancy-day = (High electrical cost - low electrical cost) ÷ (High month occupancy days - low month occupancy days)
= ($11,575 - $2,450) ÷ (4,350 - 700)
= $9,125 ÷ 3,650
= $2.50 per occupancy days
Now the fixed cost equal to
= High electrical cost - (High month occupancy days × Variable cost per occupancy days)
= $11,575 - (4,350 × $2.50)
= $11,575 - $10,875
= $700
The other factors other than the occupancy days affect the variation in electrical costs from month to month is the number of days present in a month as it remains fixed with respect to the occupancy , seasonal factors like winter or summer as in the summer the electrical cost is high as compared in the winter season , and the Systematic factors like guests, switching off fans and light depend on their wish or as per usage.
