I found the correct answer by working the answers backward, but I would like to know how to write out the steps the correct way.  (An instrument store gives a 10% discount to all students off the original cost of an instrument. During a back to school sale an additional 15% is taken off the discounted price. Julie purchases a flute for $306. How much did it originally cost?)  <BR>\n" );
