A.$9,314.45.

Step-by-step explanation:

The formula for the calculationg of the payment amount during the loan amortization: A = P * (r*( 1+r )^n /(( 1+r )^n - 1 )). Here: A = $1,595.85, n = 12 x 30 = 360, p = 6.25 % so r = 0.0625 : 12 = 0.0052, Therefore: 1,585.95 = P * ( 0.0052 * 1.0052^(360) / 1.0052^(360) ) ; 1585.95 = P * ( 0.0052 * 6.4698 / 5.4698 ) : P = 1,585.95 : 0.0061; P = $259,185.55. Finally the down payment is: 268,500 - 259,185.55 = $9,314.45. A ) $9,314.45.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
