Answer: The company will record a depreciation of $375 as depreciation.
We begin by calculating the depreciable value of the asset.


The depreciable value is $12,000.
The useful life of the asset is 8 years from the date of purchase.
So, the depreciation for one year will be
.

If a shopkeeper starts to sell the new football, their weekly margins would be:
300 x 40 = $12,000

100 x 20 = $2,000 every week
Hence, the total margin we can generate by selling every week by selling the new footballs is:
12,000-2,000 = $10,000
This means the shopkeeper should actually start selling new footballs since their shop will become more profitable
