Answer:
Salaries Payable = 3400
Step-by-step explanation:
The unpaid salaries for the week or the balance of the salaries payable can be calculated by multiplying the salary per day by the number of days worked in the week till the end of the accounting period. Thus, we will multiply 850 which is the salary per day by 4 as from Monday to Thursday, 4 work days have passed.
Salaries Payable = 850 * 4
Salaries Payable = 3400
