The present value of the cash flows is 51020.41
<h3>What is Compound Interest?</h3>
Compound interest, often known as interest on principal and interest, is the adding of interest to the loan or deposit principal. It occurs when interest is reinvested, added to the lent capital instead of being paid out, or the borrower is required to pay it, resulting in the next period's interest being generated on the principal amount plus any accumulated interest.
In the question it is given that:
Equipment cost $45,000.
first year's cash flow was $25,000
second-year cash flow $30000
5% interest is charged.
We are aware that the following relationship can be used to calculate the present value.

PV stands for present value, Future Value is FV, and the rate of interest is r.
Consequently, the present value is calculated as

⇒ PV = 51020.41

Calculation to determine How much taxable gain will Mark recognize from the sale
Mark allocated precontribution gain $20,000

($20,000+$4,000)
Therefore How much taxable gain will Mark recognize from the sale is $24,000
Answer:
The correct answer is d) product life-cycle.
Explanation:
The life cycle of a product is the evolution of sales of that product during its permanence in a given market. Depending on the product and the sector, its useful life may be greater or lesser. In addition, other factors also influence such as the administration's policies in the area where the product is marketed.
A product since it appears in the market does not always maintain the same sales trend. There are fluctuations that have to do with demand but can also influence other issues such as those related to legislation.
With regard to demand, it can happen, for example, that a product goes out of style or is replaced by a new one that meets the needs of the former. E.g. Think of the music player market, how many have we met? From the walkman, through the discman, then the Mp3, Mp4, Ipod, and even the mobile phone as a player. We can say that the discman, for example, had a fairly short life cycle.
In this regard in Economics there is a theory that explains the stages through which a product passes with respect to its production and sales, it is known as the theory of the life cycle of a product. It was defined by the American economist Raymond Vernon who assured that every product or service undergoes a similar market evolution.
