You can put this solution on YOUR website!
let x=1+decimal of the tax.
\n" ); document.write( "7.85x=8.3
\n" ); document.write( "7.85x/7.85=8.3/7.85
\n" ); document.write( "x= 1.057
\n" ); document.write( "tax=(1.057-1)*100
\n" ); document.write( "=.057*100
\n" ); document.write( "5.7%
\n" ); document.write( ".
\n" ); document.write( "To calculate a 15% tip on 8.30:
\n" ); document.write( "move the decimal point one to the left (.83) and add 1/2 the result to the result. .83+.41=1.24 est.
\n" ); document.write( "Be a big spender and give $1.25
