You plan to work for 40 years and then retire using a 25-year annuity. you want to arrange a retirement income of $4000 per month. you have access to an account that pays an apr of 6.0% compounded monthly. this requires a nest egg of $620,827.46.

what monthly deposits are required to achieve the desired monthly yield at retirement? (round your answer to the nearest cent.)

  $311.74

Step-by-step explanation:

A financial calculator computes the payment amount to be $311.74.

___

Your graphing calculator may have the capability to do this. Certainly, such calculators are available in spreadsheet programs and on the web.

___

The appropriate formula is the one for the sum of terms of a geometric series.

  Sn = a1·((1+r)^n -1)/(r) . . . . . where r is the monthly interest rate (0.005) and n is the number of payments (480). Filling in the given numbers, you have ...

  $620827.46 = a1·(1.005^480 -1)/.005 = 1991.4907·a1

Then ...

  $620827.46/1991.4907 = a1 ≈ $311.74

the answer is d on edge

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
