Suppose you decide to invest in an annuity that pays 5% interest, compounded semiannually. How much money do you need to invest semiannually to reach a savings goal of $300,000 at the end of 25 years.

In order to reach the target amount in 25 years with 5% interest we need to invest 87,282.8838 $.

Step-by-step explanation:

To find out the amount to be invested we can use the compound interest formula wich is given by:

A = P(1 + r/n)^(n*t)

Where A is the final amount, in our case we want to reach a value of $ 300,000.

P is the initial amount, this is what we want to find out.

r is the interest rate, it was given to us in the question that is 5% or 0.05

n is the number of compoundings a year, since it is semiannually we know n = 2

t is the total time for wich the money will be applied, t = 25 years.

Applying these values on the formula, we have:

300,000 = P(1 + 0.05/2)^(2*25)

300,000 = P(1 + 0.025)^(50)

300,000 = P(1.025)^(50)

300,000 = P(3.4371)

P*(3.4371) = 300,000

P = 300,000/3.4371 = 87,282.8838 $

In order to reach the target amount in 25 years with 5% interest we need to invest 87,282.8838 $.

Given Information:

Interest rate = r = 5%

Compounding semi-annually  = n = 2

Accumulated amount = A = $300,000

Number of years = t = 25

Required Information

Semi-annually payment = P = ?

Semi-annually payment ≈ $87,283

Step-by-step explanation:

Accumulated and principle amounts in terms of compound interest is given by

P = A/(1 + i)^N

Where

i = r/n = 0.05/2 = 0.025

N = n*t = 2*25 = 50

P = 300,000/(1 + 0.025)^50

P ≈ $87,283

Therefore, you need to invest $87,283 two times a year for 25 years to reach a savings goal of $300,000.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
