A home is purchased for $ 794,000 with a 16% down payment. Find the monthly payment if the mortgage is 7.22% for 19 years. Round

Nadusha1986 [10]

Answer:

The monthly payment will be of $11,485.37

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

A home is purchased for $ 794,000 with a 16% down payment.

So the value of the loan, that is, the amount subject to interest, will be given by:

$P = (1-0.16)*794000 = 0.84*794000 = 666960$

How much will the interest accumulate to?

7.22% of interest means that $r = 0.0722$

19 means means that $t = 19$

Monthly means that $n = 12$

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(t) = 666960(1 + \frac{0.0722}{12})^{12*19}$

$A(t) = 2618664.5$

Monthly payment:

2618664.5 divided in 19*12 payments. So

2618664.5/(19*12) = 11485.37

The monthly payment will be of $11,485.37

A line passes through the point (-1, -9) and has a slope of -7.

tia_tia [17]

Answer:

y = -7x - 16

Step-by-step explanation:

The formula for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept. Since we already know the slope, all that is left is the value of b, which can be found by substituting the values of the point (-1, -9) into the equation and solving:

$-9=-7(-1)+b$
