Your brother has asked you for a loan and has promised to pay you $7,100 at the end of three years. if you normally invest to earn 8.20 percent per year, how much will you be willing to lend to your brother if you view this purely as a financial transaction (i. e., you don’t give your brother a special deal)? (if you solve this problem with algebra round intermediate calculations to 6 decimal places, in all cases round your final answer to the nearest penny.)

5605.01 dollars

Step-by-step explanation:

Given that after 3 years your brother will pay your 7100 dollars.

If invested otherwise, interest is 8.20 percent per year

Let P be the amount invested

Then after 3 years at compound interest final amount

A =

This must be less than or equal to 7100 if willing to lend to brother

i.e.

So willing to lend upto 5605.01 dollars

just get this app called photo math it should be able to do those

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
