Assigning dependencies for expenses

Txs Tools wants to assign a dependency for its operating expenses, particularly admin salaries.

The conditions are as follows:

Admin expenses increase in July and August (Jul and Aug) as temporary workers need to be hired to cover the summer holiday.
The increase is based on the number of employees taking holidays during that time. For the current year, the value for August is emp_leave = 6 (6 employees expected to take leave).
The cost is 80 USD per temp employee hired.
