Explanation:

A fix Payment for a specified period of time is called annuity. The discounting of these payment on a specified rate is known as present value of annuity. The value of the annuity is also determined by the present value of annuity payment.

Formula for Present value of annuity is as follow

PV of annuity = P x [ ( 1- ( 1+ r )^-n ) / r ]

Where

P = Monthly receipt = $1,225

n = number of period = 30 years x 12 month each year = 360 months

As we already have the present value of annuity we need to calculate the rate of return.

$230,000 = $1,225 x [ ( 1- ( 1+ r/12 )^-360 ) / r ]

r =  4.93

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
