Duane and thad plan on retiring 27 years from today and plan to have the same amount saved at that time. in preparation for this, duane is depositing $15,000 today at an annual interest rate of 5.2 percent. how will thad's deposit amount vary from duane's if thad also makes a deposit today but earns an annual interest rate of 6.2 percent?

Thad deposited an amount of $11,241.58 about 27 years ago,

Step-by-step explanation:

About Duane:

The amount deposited by Duane = $15,000

Time interval = 27 years

Rate = 5.2%

Now, SIMPLE INTEREST  =  

So, the SI on 15,000 after 27 years = $21,060

Now, AMOUNT = PRINCIPAL + SI

                          = 15,000 + 21,060 = $36,060

Hence, after 27 years, Duane's amount is equivalent to $36,060

Now, About Thad:

Let us assume amount deposited  = P

Rate = 6.2%

Time = 27 y

Now,

So, the SI on 15,000 after 27 years = $1.674 P

Now, AMOUNT = PRINCIPAL + SI

        $36,060  = P +  1.674 P

      or, 2.624 P =  $36,060

⇒ P = 30,060/2.624 = 11,241.58

Hence, Thad deposited an amount of $11,241.58 about 27 years ago,

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
