Final answer:
The direct expenses for a day can be calculated by dividing the total indirect expenses for the month by the number of days in the month.
Step-by-step explanation:
The direct expenses for a day can be calculated by dividing the total indirect expenses for the month by the number of days in the month. In this case, the indirect expenses for the month are $500 + $30 + $75 = $605.
Since there are 30 days in the month, the direct expenses for a day would be $605 / 30 = $20.17.
