I DON'T KNOW HOW YOU SOLVED THE PROBLEM, BUT I THINK THAT YOU GOT THE CORRECT ANSWER---------AT LEAST, WE GOT THE SAME ANSWER.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let x=number of bags of the $245 brand that are sold \n" ); document.write( "Then 19-x =number of bags of the $347 brand that are sold\r \n" ); document.write( "\n" ); document.write( "Now we know that:\r \n" ); document.write( "\n" ); document.write( "receipts for the $245 brand are 245x; receipts for the $347 brand are 347(19-x) and we are told that these add up to $5369 so our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "245x+347(19-x)=5369 get rid of parens \n" ); document.write( "245x+6593-347x=5369 subtract 6593 fron both sides \n" ); document.write( "245x-347x=5369-6593 collect like terms \n" ); document.write( "-102x=-1224 divide both sides by -102 \n" ); document.write( "x=12 bags of the $245 brand \n" ); document.write( "19-x=19-12=7 bags of the $347 brand\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
