Final answer:
To calculate the shrinkage as a percentage of sales, subtract the physical inventory value from the book value and then divide it by the total sales. In this case, the shrinkage is 2.22%.
Step-by-step explanation:
To calculate the shrinkage as a percentage of sales, you need to find the difference between the book value of the merchandise and the physical inventory value. In this case, the book value is $245,000 and the physical inventory value is $237,000, so the shrinkage is $245,000 - $237,000 = $8,000.
Next, divide the shrinkage by the total sales between inventories. The total sales is $360,000, so the shrinkage as a percentage of sales is ($8,000 / $360,000) x 100% = 2.22%.
