Algebra.Com's Answer #79978 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! your first equation is on the right track ... you have all the information in it that you need\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the sales tax is anything over the price (3*32) ... the tax rate is the tax divided by the price\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "let x=rate ... x=(99.84-(3*32))/(3*32) \n" ); document.write( " |
