Answer: $1,800
Explanation:
Operating expenses comprise of only insurance and wages.
The total operating expenses were $5,000.
Out of that $5,000, $400 was for an increase in wages, $4,000 was paid off.
The rest is therefore for insurance.
= 5,000 - 400 - 4,000
= $600
If $600 is the insurance payment during the year then on 1/1/23, the balance was the current balance plus the payment;
= 1,200 + 600
= $1,800
