Given the formula A = P(1 + )". compute A (rounded to two decimal places) if P = 10,000,7
Flura [38]

Answer:

A = 16010.32

Step-by-step explanation:

Given that,

A=P(1+\dfrac{r}{k})^n

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

A=10,000(1+\dfrac{0.08}{2})^{12}\\\\=10,000\times (1.04)^{12}\\\\=16,010.32

So, the value of A is 16010.32. Hence, the correct option is (B).

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.
N76 [4]

The monthly payment amount is $860.25.

Step-by-step explanation:

Step 1; The bank offers an amount of $195,000 with an APR of 5.3%. This means that the family must pay 5.3% of the $195,000 every year for 30 years. To calculate we must determine how much 5.3% of $195,000 is. To do that we make 5.3% a fraction by dividing it by 100 and multiplying it with the amount.

5.3% of $195,000 = \frac{5.3}{100} × $195,000 = 0.053 × $195,000 = $10,335 per year.

Payment owed for 30 years = Payment owed a year × 30

                                               = $10,335 per year × 30 = $310,050 for 30 years.

Step 2; To find the monthly payments we need to know how many months are in a 30 year period. Months in 30 years = 30 × 12 months = 360 months. The monthly payment is, therefore, payment owed in 30 years divided by the months in that 30 year period.

Monthly payment = $10,335 / 360 = $ 861.25.

So the family must pay a monthly payment of $861.25 for 30 years.
