Step-by-step explanation:

• Write the Formula

Depreciation=(Value of the Asset-Salvage Value)/Useful Years

• Substitute the given to the formula ypu had written

Depreciation=(PHP20,000-PHP1,000)/8 years

• Proceed with normal mathematical operations

Depreciation=PHP19,000/8 years

Depreciation= PHP2,375

• Deduct the depreciation expense times the number of years according to the given problem. This was not very clear to me in the problem you had given. Was it any value less than 8?

Example: The value of the machine after 3 years, same problem above.

PHP19,000-(PHP2,375*3)

PHP19,000-(PHP7,125)

=PHP 11,875
