Mahmoud will be needing many things such as. A loan of money , Maybe a wed site to spread him company so more people can see it and materials to build chairs such as wood , springs , foam.
Solution :
Given :
The bonds offer a 
of 4.5% per year
Tax rate = 10% = 0.10
Inflation rate = 2
= + 
= 2 + 4.5
= 6.5
= 
= 
= 5.85
After tax real interest rate = 
-
= 5.85 - 2.0
= 3.85
= 7.0
= +
= 7 + 4.5
= 11.5
= 
= 10.35
= 11.5 x (1 - 0.10)
= 11.5 x 0.90
= 10.35
= -
= 10.35 - 7.0
= 3.35
Putting all the value in table :
Real interest Nominal interest After tax nominal After tax
rate rate interest rate interest rate
2.0 4.5 6.5 5.85 3.85
7.0 4.5 11.5 10.35 3.35
Comparing with the 
, a 
will increase the after after tax real interest rate when the government taxes nominal interest income. This tends to encourage saving, thereby increase the quantity of investment in the economy and the increase the economy's long-run growth rate.
State Capitalism or a Centrally Planned Economy
Answer:
The correct answer is C. firm to the environment.
Explanation:
Currently, when a company begins its usual operations and the one that it will play day by day throughout its existence, it cannot leave aside knowing the role of its company, the environment in which it develops its function as a company or its operation with the environment , and it is essential that the company meets the social responsibility to which it is obliged.
It should always be taken into consideration that the life of the human being is greatly influenced and affected by the environment that surrounds it, so that the proper development and even its survival, depends entirely on the relationship between the company and The environment around us. And as with a coin, which has two sides, exactly the same thing happens between business and environment relationships, since on the one hand our environment provides us with the energy and resources we need to take advantage of them in Our business operations.
While on the other hand, man is also exposed to the possible aggressions that occur in the environment, as in the case of floods, pests, diseases, inclement weather or deprivation of resources, between others. The problem with this is that in our current society, the more it produces the more resources are needed, and the more it consumes the more waste and garbage is generated.
The break-even point in units using the mathematical equation is 2,000 in units and the unit contribution margin is 80 per unit.
<h3>Break even points in units</h3>
a. Break-even point in unit
Using this formula
Break-even point in unit=Fixed cost/(Selling price-Variable cost)
TC = FC + VC
Sales - TC = Net Income
Sales - TC = 0
Sales - FC - VC = 0
2500(Q)-160,000-170(Q) = 0
80(Q)-160,000 = 0
80(Q)=160,000
Q=160,000/80
Q=2,000 break-even in units
b. Unit contribution margin
Unit contribution margin = Selling price- Variable cost
Unit contribution margin= $250 - $170
Unit contribution margin =$80 per unit
Inconclusion the break-even point in units using the mathematical equation is 2,000 in units and the unit contribution margin is 80 per unit.
