To calculate the increased cost of funds tied up in accounts receivable, we need to determine the increase in accounts receivable and then calculate the cost of funds for that increase.
The increase in accounts receivable can be calculated by subtracting the initial sales from the final sales:
Increase in accounts receivable = Final sales - Initial sales
Increase in accounts receivable = $6,120,000 - $4,110,000
Increase in accounts receivable = $2,010,000
Next, we can calculate the cost of funds tied up in accounts receivable by multiplying the increase in accounts receivable by the opportunity cost of funds:
Cost of funds tied up in accounts receivable = Increase in accounts receivable * Opportunity cost of funds
Cost of funds tied up in accounts receivable = $2,010,000 * 0.10
Cost of funds tied up in accounts receivable = $201,000
Therefore, the increased cost of funds tied up in accounts receivable is $201,000.
