If you add all of the digits of a number, and it's divisible by 3, the entire number will be divisible by 3. If the number is divisible by 2 and 3, it's divisible by 6 as well. If the digits of a number add up to a number divisible by 9, the whole number will be divisible by 9.

The Hughes purchased a new condo for $ 1,000,000. at 8 % for 30 years. What is the monthly payment?

viktelen [127]

We know that

P = A/D
Where,
P = monthly payments,
A = Total amount =$1,000,000
$D=[(1+r/12) ^{12*t}-1]/[(r/12)*(1+r/12)^{12*t}]$

in this problem

t=30 years
r=8%----> 0.08

$D=[(1+0.08/12) ^{12*30}-1]/[(0.08/12)*(1+0.08/12)^{12*30}] =136.2835$

$P=1000000/136.2835-----\ \textgreater \ P=$7337.65$

the answer is
$7337.65
