Answer:
The turnover ratio is 10.7
Explanation:
Turnover ratio may be defined as the ration of net credit sales with the average accounts receivable.
The formula used to calculate the turnover ratio is :
Net credit sales (2019)= $1,022,000
Average account receivables = 
=94750.
![\text{Turn over ratio}=[tex]\frac{1,022,000}{94750}](https://tex.z-dn.net/?f=%5Ctext%7BTurn%20over%20ratio%7D%3D%5Btex%5D%5Cfrac%7B1%2C022%2C000%7D%7B94750%7D)
= 10.7
Hence, The turn over ratio is 10.7.
