To calculate the accounts receivable turnover ratio for Years 2 and 3, we use the formula:
\[ \text{Accounts Receivable Turnover Ratio} = \frac{\text{Net Credit Sales}}{\text{Average Accounts Receivable}} \]
Where the average accounts receivable is calculated as:
\[ \text{Average Accounts Receivable} = \frac{\text{Accounts Receivable at the beginning of the year} + \text{Accounts Receivable at the end of the year}}{2} \]
To convert the turnover ratio to days, we use:
\[ \text{Days in Period} = \frac{365}{\text{Accounts Receivable Turnover Ratio}} \]
To find the average accounts receivable for Year 2 and Year 3, we use the formula:
\[
\text{Average Accounts Receivable} = \frac{\text{Accounts Receivable at the beginning of the year} + \text{Accounts Receivable at the end of the year}}{2}
\]
For Year 2:
\[
\text{Average Accounts Receivable}_{\text{Year 2}} = \frac{74,800 + 76,800}{2} = 75,800.0
\]
For Year 3:
\[
\text{Average Accounts Receivable}_{\text{Year 3}} = \frac{76,800 + 89,100}{2} = 82,950.0
\]
The accounts receivable turnover ratio is calculated using the formula:
\[
\text{Accounts Receivable Turnover Ratio} = \frac{\text{Net Credit Sales}}{\text{Average Accounts Receivable}}
\]
For Year 2:
\[
\text{Accounts Receivable Turnover Ratio}_{\text{Year 2}} = \frac{660,000}{75,800.0} \approx 8.707
\]
For Year 3:
\[
\text{Accounts Receivable Turnover Ratio}_{\text{Year 3}} = \frac{907,000}{82,950.0} \approx 10.93
\]
To convert the turnover ratio to days, we use the formula:
\[
\text{Days in Period} = \frac{365}{\text{Accounts Receivable Turnover Ratio}}
\]
For Year 2:
\[
\text{Days}_{\text{Year 2}} = \frac{365}{8.707} \approx 41.92 \text{ days}
\]
For Year 3:
\[
\text{Days}_{\text{Year 3}} = \frac{365}{10.93} \approx 33.38 \text{ days}
\]
\[
\boxed{\text{Year 3: 10.93 times}}
\]
\[
\boxed{\text{Year 2: 8.71 times}}
\]
\[
\boxed{\text{Year 3: 33.38 days}}
\]
\[
\boxed{\text{Year 2: 41.92 days}}
\]
