Algebra.Com's Answer #171730 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! OK \n" ); document.write( "Let x=cost of dinner before tax and tip \n" ); document.write( "Then 0.06x=sales tax \n" ); document.write( "Cost of dinner after 6% sales tax would be (x+0.06x) or (1.06x) \n" ); document.write( "The 15% tip would be 0.15(1.06x) or 0.159x \n" ); document.write( "Then total cost would be: \n" ); document.write( "x+0.06x+0.159x and this would equal $97.52. So our equation to solve is: \n" ); document.write( "x+0.06x+0.159x=$97.52 collect like terms \n" ); document.write( "1.219x=$97.52 divide each side by 1.219\r \n" ); document.write( "\n" ); document.write( "x=$80--------------------------cost of dinner before tax and tip\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
