The monthly mortgage payment on your house is $821.69. it is a 30 year mortgage at 6.5% compounded monthly. how much did you borrow? 1. $ 85,000 2. $100,000 3. $115,000 4. $130,000 5. $140,000

The formula for figuring the monthly payments on such a loan is

... A = P(r/12)/(1 -(1 +r/12)^(-12t))

where r is the annual interest rate (.065), P is the principal amount (we want to find), t is the number of years (30), and A is the monthly payment.

Filling in the given values, we have

... 821.69 = P(.065/12)/(1 - (1 +.065/12)^(-12*30)) = 0.00632068·P

Then the principal amount is

... P = 821.69/0.00632068 = 130,000.25

The most appropriate choice is ...

... 4. $130,000

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
