Final answer:
The crossover point occurs at 6,363.64 room nights. Since Tim expects to rent 18,250 room nights annually, outsourcing the cleaning services to Duffy's Maid Service is the best option.
Step-by-step explanation:
The crossover point is when the costs of cleaning rooms internally equal the costs of outsourcing the cleanup. To find the crossover point, we need to compare two cost equations - the cost of internal cleaning and the cost of outsourcing to Duffy's Maid Service:
Cost of Internal Cleaning: Total cost = Fixed Cost + (Variable Cost per Room x Number of Rooms)
Cost of Outsourcing: Total cost = Fixed Cost + (Cost per Room x Number of Rooms)
For Tim's internal cleaning, the fixed cost is $61,000 and the variable cost is $12.50 per room. Duffy's fixed cost is $26,000 and the cost per room is $18.00.
The equations are:
- Internal: $61,000 + $12.50x
- Duffy's: $26,000 + $18.00x
By equating the two:
$61,000 + $12.50x = $26,000 + $18.00x
$61,000 - $26,000 = $18.00x - $12.50x
$35,000 = $5.50x
x = $35,000 / $5.50
x = 6,363.64
Since Tim rents an average of 50 rooms for 365 nights, totaling 18,250 room nights a year, we compare this to the crossover point. If Tim's annual room nights are less than 6,363.64, then internal cleaning is the best option; if more, outsourcing is the better option.
As 18,250 is higher than 6,363.64, outsourcing the cleaning services to Duffy's Maid Service is the best option for Tim.
