A company charging a customer 6percent interest on invoices that are not paid on time receives interest for r 15.65 from a customer whose account was 75 days overdue.what was the outstanding amount?1. R 1070.50. 2.r 1269.39. 3.1540.60. 4.1750.30.

Since the equation to calculate interest is:
Principal * Rate * Time = Interest.
