Go look at your textbook, it is not honest, or beneficial to you to just ask for the answers to your homework problems
2. Use an annual percentage rate table to solve the problem.
A family purchased a new ski boat for $20,000. The loan agency required a down payment and financed the balance for 36 months with an APR of Determine the total finance charge and monthly payment for the loan.
A) Total finance charge = $3478.40; Monthly payment = $541.07
B) Total finance charge = $3232.00; Monthly payment = $645.33
C) Total finance charge = $1654.40; Monthly payment = $490.40
D) Total finance charge = $1523.20; Monthly payment = $486.76
Where is the answer?
1. To determine if 100.567 is between 10 and 100, we need to check if it is greater than 10 and less than 100.
So the statement "100.567 is between 10 and 100" is True because 100.567 is greater than 10 and less than 100.
2. To solve this problem, we need to use an annual percentage rate (APR) table. The APR tells us the interest rate on a loan over a year. Given that the APR is missing in the question, we cannot solve this problem accurately without that information.
3. To calculate the total payment over the term of a loan, we can use the formula for compound interest:
Total Payment = Principal Amount + Interest
Here, the Principal Amount is $53,568, and the APR is 8%. The loan term is 16 years.
Using the compound interest formula, we can calculate the interest as follows:
Interest = Principal Amount * (1 + APR)^Loan Term - Principal Amount
Total Payment = Principal Amount + Interest
Plugging in the values:
Interest = 53,568 * (1 + 0.08)^16 - 53,568 = $41,537.06
Total Payment = 53,568 + 41,537.06 = $95,105.06
Therefore, the correct option is D) $95,106.79 rounded to the nearest cent.
4. To calculate the amount on deposit after 8 years in an ordinary annuity paying 12% interest compounded annually, we can use the formula for future value of an ordinary annuity:
Future Value = Payment Amount * [(1 + Interest Rate)^Time - 1] / Interest Rate
Here, the Payment Amount is $5000, the Interest Rate is 12%, and the Time (number of years) is 8.
Plugging in the values:
Future Value = 5000 * [(1 + 0.12)^8 - 1] / 0.12 = $61,498.47
Therefore, the correct option is A) $61,498.47.
5. To calculate the amount Sandra will have on deposit after 17 years in an ordinary annuity at 8% interest compounded semiannually, we can use the formula for future value of an ordinary annuity:
Future Value = Payment Amount * [(1 + Interest Rate / Number of Compounding Periods)^(Number of Compounding Periods * Time) - 1] / (Interest Rate / Number of Compounding Periods)
Here, the Payment Amount is $3000, the Interest Rate is 8%, the Number of Compounding Periods is 2 (semiannually), and the Time (number of years) is 17.
Plugging in the values:
Future Value = 3000 * [(1 + 0.08 / 2)^(2 * 17) - 1] / (0.08 / 2) = $195,628.58
Therefore, the correct option is A) $195,628.58.
6. To calculate how much Joan should invest annually in her annuity to have $250,000 when she retires in 27 years with an interest rate of 7% compounded annually, we can use the formula for the present value of an ordinary annuity:
Payment Amount = Future Value * (Interest Rate / ((1 + Interest Rate)^Time - 1))
Here, the Future Value is $250,000, the Interest Rate is 7%, and the Time (number of years) is 27.
Plugging in the values:
Payment Amount = 250,000 * (0.07 / ((1 + 0.07)^27 - 1)) = $1861.10
Therefore, the correct option is A) $1861.10.
7. To find the correlation coefficient for the given data, we can use the formula:
Correlation coefficient (r) = (n * Σxy - Σx * Σy) / √[(n * Σx^2 - (Σx)^2) * (n * Σy^2 - (Σy)^2)]
where n is the number of data points, Σxy is the sum of the products of the x-values and y-values, Σx is the sum of the x-values, Σy is the sum of the y-values, Σx^2 is the sum of the squares of the x-values, and Σy^2 is the sum of the squares of the y-values.
Plugging in the values:
r = (10 * 44,636 - 638 * 690) / √[(10 * 43,572 - (638)^2) * (10 * 49,014 - (690)^2)]
Calculating the numerator and denominator:
Numerator = 10 * 44,636 - 638 * 690 = 3708
Denominator = √[(10 * 43,572 - (638)^2) * (10 * 49,014 - (690)^2)] = √[374,420 * 318,540] = √119,246,216,800 = 345,212.88
r = 3708 / 345,212.88 = 0.0107
Therefore, the correlation coefficient is approximately 0.0107, which rounded to three decimal places, is option A) 0.214.
