Answer:
Step-by-step explanation:
Let's find our C value for the quadratic equation.
That is our C. Since we added 9 to one side, we have to do the same to the other. We get:
Now, lets form the left side as a binomial squared.
Let's square both sides now:
Now, we subtract 3 from both sides to isolate the variable, X:
This means that the answers are:
I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
Johnson's will pay by the end of the 20-year loan $326,807.25
Johnson's will pay by the end of the 30-year loan $512,109.68
Step-by-step explanation:
The formula for compound interest, including principal sum is
, where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount (the initial deposit or loan amount)
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
The Johnson's are buying their first home. They are contemplating
two similar loans
The first is a 30-year loan for $150,000 at an interest rate of 4.1% APT
compounded monthly
∴ P = $150,000
∴ r = 4.1% = (4.1/100) = 0.041
∴ n = 12 ⇒ compounded monthly
∴ t = 30
- Substitute all of these values in the formula above
∴
∴ A = $512,109.68
Johnson's will pay by the end of the 30-year loan $512,109.68
The second is a 20-year loan for a $150,000 at an interest rate of 3.9%
APR compounded monthly
∴ P = $150,000
∴ r = 3.9% = (3.9/100) = 0.039
∴ n = 12 ⇒ compounded monthly
∴ t = 20
- Substitute all of these values in the formula above
∴
∴ A = $326,807.25
Johnson's will pay by the end of the 20-year loan $326,807.25
