Answer:

Step 2 is incorrect

Step-by-step explanation:

Step 2 is incorrect

step 1: 3x + 15 = 2x + 35

The amount of money that John would have in his account when he is ready to retire is $6,351,400.21.

<h3>How much would be in the retirement account?</h3>

The formula that can be used to determine the future value of the annuity is

Future value = Daily deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = 3.5 / 365 = 0.0096%
n = (65 - 48) x 365 = 6205

Annuity factor = [(1.000096^6205) - 1] / 0.000096 = $8468.53

Future value = 750 x $8468.53 = $6,351,400.21
