Well, this is rather lengthy so...
First, you'd do...
1000 * 0.073 = $73.
$73 is for one quarter, so...
A quarter of a year is 1/4 of the year, so you'd need to do... $73 * 4.
= $292.
$292 is for one year.
Now do...
$292 * 30
Your Answer:
A. $8760 is invested at an interest rate of 7.3% compounded quarterly for 30 years.
