Last month, you lent a work colleague $5000 to cover some overdue bills. He agreed to pay you in 1 month with interest at 2% for

Answer:

The present value of the cash flow, discounted at a 5% annual rate, is $76,815.65.

Explanation:

First, we calculate the present value of a $15,000 annuity over 4 years:

C 15,000.00

Time 4

Rate 0.05

PV $53,189.2576

Next, we discount two additional years as a lump sum, corresponding to two years following the investment:

Maturity  53,189.26

Time  2.00

Rate  0.05000

PV   48,244.2245

Adding them results in the present value:

48,244.22 + 28,571.43 =  76,815.65  

Natalie intends to achieve a 25% profit on a sale of $70,000. To calculate, she does the following:

(125 ÷ 100) × 70000 = $87500.

Natalie aims for $87500, however, the agent will take a 6% commission on the sale price, so she must include this amount, calculated as:

(106 ÷ 100) * 87500 = $92750.

For the total of $92750, there is an additional closing cost of $1200,

This gives us $92750 + $1200 = $93950.

When rounding $93950 to the nearest hundred, we arrive at $94000.

Therefore, to secure a 25% profit, Natalie should set the final sale price at $94000.

A Decision Support System (DSS) is an interactive information framework comprising hardware, software, data, and mathematical and statistical models designed to aid decision-makers within an organization. The components of a DSS include a database, model base, and a user interface. DSS requirements stipulate that it must be interactive, integrate the human factor along with hardware and software, and utilize both internal and external data.
