.423    is   423/1000   and rational

30 / (1/6)  =  (30/1) / (1/6)  =  30/1  x  6/1  = 180

($248.55 + 306.81 +61.97)(.85) (1.06) = $ 556.21

So......you are supposed to get equal payments annually for 30 years to a balance of zero, with the balance gaining value at 6% per year......do I have that correct?

Inflation has been pretty low over the last 10 years High 3.8  low -.4)

.....what does your account mean when it says 'indexed for inflation'

Your payments go DOWN with inflation? 

I would certainly press a little harder for clarification from your agent about the values used for inflation....'calculated by a computer' should make it even easier to get the numbers used yearly !

  There are some financial gurus online here that will be able to give you some better/good answers.....

Without inflation, compounded annually at 6%, annual payments for 30 years to balance of zero should yield payments of:

47221.79  as you found

Since you are having difficulties finding 'X'. I highlighted them for you......you're welcome

87*4/87(9.27*X)+-62+532*12/X=4852941

#1   .08      eight hundredths

#1 4237 = 4.237 x 10^3

I think you can see how to do the rest.......it is, afterall YOUR homework !

I'll show you how to do the first one

   1)     4 x 10^7      x    2x10^8      =   (4x2) x 10^(7+8)  =   8 x 10^15

Do you see?

250 million    and 5 billion     

250 million = 250 000 000 = 2.5 x 10^8    5 billion = 5 000 000 000  = 5 x 10^9  

    10^8 and 10^9   differ by 10^1 = a factor of 10      

(though it is actually 20... but I am not sure that was what was asked...I think they just wanted you to compare the 10 exponents)

5000000000/250000000 =  20

I did not know that !      Cool.

cups   /   cups/batch    =  cups  x   (batch/cup) = batch (see how the 'cups' cancels?? and you are left with batches??))

8/3 cups  /  2/3 cups/batch   =

8/3  /   2/3    =   8/3 x 3/2 = 24/6 = 4 complete batches

LOL...I found an online calculator that gave THIS as answer...getting on up towards infinity
