Let
\n" ); document.write( "Original Price of Coat = x
\n" ); document.write( "5% of x = 5%*x = (5/100)*x = 1/20 * x = x/20\r
\n" ); document.write( "\n" ); document.write( "Total Cost = Original Price + 5% of original Price
\n" ); document.write( "140.25=x+(x/20)
\n" ); document.write( "Multiply by 20 both sides
\n" ); document.write( "20*140.5 = 20x+x
\n" ); document.write( "2810=21x
\n" ); document.write( "2810/21=21x/21
\n" ); document.write( "133.81= x
\n" ); document.write( "x=133.81
\n" ); document.write( "Original Price of Coat = x = 133.81
\n" ); document.write( "Tax paid = Amount paid - original price
\n" ); document.write( "Tax paid = 140.50- 133.81
\n" ); document.write( "Tax paid = 6.69\r
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "=====
\n" ); document.write( "original pirce = 133.81
\n" ); document.write( "5% of original price = 5% * 133.81 = 0.05 * 133.81 = 6.69\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
