Final answer:
To calculate the accounts receivable turnover, divide net credit sales by average accounts receivable.
Step-by-step explanation:
To calculate the accounts receivable turnover, we need to divide the net credit sales by the average accounts receivable. Net credit sales is the difference between total sales and cash collected. In this case, the net credit sales would be $900,000 - $850,000 = $50,000.
The average accounts receivable can be calculated by adding the beginning and ending accounts receivable and dividing by 2. Therefore, the accounts receivable turnover would be $50,000 / (($100,000 + $100,000) / 2) = 0.5.
