The ability to forecast cause and effect is crucial for a solid economic model since it enables it to both explain past events and foresee potential future ones.
A model of the economy's importance
Its main goal is to describe and examine the prices and volume sold in a market that is competitive. In relation to price and other factors, the equations of the model define the level of supply and demand (for example, income).

Answer:
Gain from sale = $23,067
Explanation:
the none interest bearing note must be recorded at present value:
present value of the note = face value / (1 + r)ⁿ
- face value = $253,240
- r = 11%
- n = 3
PV = $253,240 / (1 + 11%)³ = $185,167
the note receivable must be recorded at $253,240, but $68,073 will be recorded as interest revenue. 
the journal entry for the transaction should be:

The stock price is mathematically given as
P=$57.64
<h3>What is the 
stock price?</h3>
Generally, the equation for is Value after year   mathematically given as

V= $1454.25
Hence, the current value is mathematically given as
I=Discounting factor equal to the future cash flows multiplied by their present value

I=$1063.508769
current value for ordinary stock
I'=$1037.508769million
In conclusion, the stock price is 
P=(1037.508769/18)
P=$57.64

Answer:
A. $6,400
B. $240
C. $1,000,000
D. $30,000
Explanation:
Requirement A, C, and D:
Prizes and awards are taxable income for a taxpayer. Any awards or prizes won from the lottery or television should be added to the income. Therefore, the Winning lottery is a taxable income for Kerry, $1,000,000. Again, Receiving the award for scientific research is also taxable income for Deborah, $30,000.
The winning award for accomplishments is also a taxable income. So, receiving a $6,400 worth gift bag is a taxable income for Cheline.
Requirement B:
There is an exception if the award is for tangible property and a long-years of accomplishment. At that time, the taxpayers will be excluded from some part of the necessary amounts to be paid as tax. If it is not a qualified award, the exclusion will be $400. If it is qualified, the tax exclusion is 1,600. Since Jon received a gold watch for 25 years of service and the gift is not qualified, he has to pay tax for $(660 - 400) = $240.
