Does anyone know what the monthly payment is?:/

====================================================

Explanation:

The formula given is

which to be honest is a big ugly mess of variables. The fractions also make things even more messy. Through trial and error, you can find various ways to help clean up the formula.

Notice how the "r/12" seems to show up a lot. Let's replace that fraction with the variable A.

So we'll make A = r/12

Because of that, the expression turns into

After replacing all the "r/12" terms with "A", we have the formula

turn into

which is a bit simpler in my opinion.

------------------

We could also let

B = (1+A)^(12t)

which would then allow us to go from this

to this

and that's even more simple

---------------------

We're given the following values

Based on those values, we can say

From here, we plug the values of P, A, and B into the simplified version of the formula below.

The monthly payment is roughly $700.22

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
