Question 4700
The answer is $306.31  the amount owned, this is principal + interest.

$290.00 + $16.31= $306.31

formula in simple interest: 
 I=  P*R/t

Where:
                
I= Simple interest     P= Principal    R=  annual rate  t= time




So if we have  
    I= $290*7.5%/12  = 21.75/12 = 1.81*9= $16.31
     


So, Total amount owned is    A= P+I   ,   A= $290+$16.31,  A=$306.31
Where:  A= Total amount,  P= Principal,  I= interest
