If the annual simple interest is 1.2% then, the monthly interest would be 0.1%. The amount of interest, I, that needs to be paid is calculated through the equation,
                                 I = P x r
where P is the principal. In this case, P is the unknown average balance last month, r is the rate. 
                                 1.25 = P x 0.001
P from the equation above is equal to $1,250. Thus, the answer to this item is letter C.
