Hi can come someone clarify something for me?

Hi can come someone clarify something for me? In this question, A new medical practice purchases computer equipment that cost$15,000, to be used for medical billing. In addition, the practice purchases billing software that cost $5,000. Both the computer equipment and the software are expected to have 3-year useful

lives and no salvage value. Calculate the 3 years of depreciation,

using SL, DDB, and SYD?

My question is, is the total cost of the assets $20,000?
