Solution

Given that:

Tony saved an amount of money =$125,500

Investment generates a =10% compounded monthly

A monthly income of =$1350

Now, we have to find How many months will Tony have this income coming to him

Thus

The current  income value will be equal to = $125,500.

So,

125,500 = 1350 + 1350/1.0077 + 1350/1.0077^2 + 1350/1.0077^3 + ... + 1350/1.0077^n

125,500 = 1350 * 1.0077 / 0.0077 * ( 1 - (1/1.0077)^n )

Therefore n= 162 months
