To calculate: The monthly interest rate and then write a recursive rule for the amount of money owe after n months. It is given that you take out a five years loan of $10,000 to buy a car. The loan has an annual interest rate of 6.5% compounded monthly. Each month you make a monthly payment of $196.
The interest rate is
Given information:
It is given that you take out a five years loan of $10,000 to buy a car. The loan has an annual interest rate of 6.5% compounded monthly. Each month you make a monthly payment of $196.
Calculation:
Consider the given information.
The loan has an annual interest rate of 6.5% compounded monthly, so the monthly interest rate is
The loan amount was $10,000 and in the second month the monetary debt will increase by
So, the recursive rule can be
ii.
To calculate: The amount owes after 12 months.
After 12 months the amount owe is $8395.135 approximately.
Given information:
It is given that you take out a five years loan of $10,000 to buy a car. The loan has an annual interest rate of 6.5% compounded monthly. Each month you make a monthly payment of $196.
Calculation:
Consider the given information.
Step 1: Enter the value of
Step 2: Enter the formula “=1.0054*A1-196” into cell A2 and fill down command to copy the recursive equation into the rest of column A.
After 12 months the amount owe is $8395.135 approximately.
iii.
To calculate: The number of months to repay the loan if you had decided to pay an additional $50 with each monthly payment.
47 months are required to pay the loan.
Given information:
It is given that you take out a five years loan of $10,000 to buy a car. The loan has an annual interest rate of 6.5% compounded monthly. Each month you make a monthly payment of $196.
Calculation:
Consider the given information.
The recursive rule was
Now if paying $50 more then the new recursive rule will be:
New rule:
By using the graphing utility:
Thus, it required 47 months to repay the loan because the first term less than 0 is
iv.
To identify: That is, it beneficial to pay the additional $50 with each payment.
Yes, it is beneficial to pay the additional $50.
Given information:
It is given that you take out a five years loan of $10,000 to buy a car. The loan has an annual interest rate of 6.5% compounded monthly. Each month you make a monthly payment of $196.
Explanation:
Consider the given information.
It is beneficial to pay the additional $50 because the monthly rate increases the det each month.
If $50 extra will be paid then they need to pay less interest and will repay it faster and have less increases.
