Answer:
Interest rate = 10.94%
Explanation:
The future value is the estimated worth of an investment at a specified time assuming a particular interest rate. The present value is the initial amount invested.
For Towne station the future value of their investment is $31,406, and three years ago they put in $23,000.
To get the interest rate we will use the following formula
Future value= Present value* {(1+ interest rate)^number of years}
31,406= 23,000* {(1+Interest rate)^3}
Interest rate = 0.1094~10.94%
