How many compact discs did you buy that cost $10.50?  How many did you buy that cost $8.50?  I was able to get the answer by process of elimination but I need to figure out how to get the answer using linear equations and and inequalities, I need to see the work so that I can learn how to do this.    Thank You Very Much. </SPAN>\n" );
