A 5% sales tax on a $10 item is:
\n" ); document.write( "\"+.05%2A10+=+.5+\" or $.50
\n" ); document.write( "After tax it casts $10.50
\n" ); document.write( "-----------------------
\n" ); document.write( "The $10 item with a 30% discount
\n" ); document.write( "before tax costs:
\n" ); document.write( "\"+10+-+.3%2A10+=+10+-+3+\"
\n" ); document.write( "\"+10+-+.3%2A10+=+7+\" or $7
\n" ); document.write( "and
\n" ); document.write( "\"+7+%2B+.05%2A7+=+7+%2B+.35+\"
\n" ); document.write( "\"+7+%2B+.05%2A7+=+7.35+\" so
\n" ); document.write( "the item costs $7.35 after tax
\n" ); document.write( "---------------------
\n" ); document.write( "As for what they want:
\n" ); document.write( "So, the sales tax before the discount
\n" ); document.write( "was $.50
\n" ); document.write( "The sales tax after the discount
\n" ); document.write( "was $.35
\n" ); document.write( "----------------------
\n" ); document.write( "\"+.5+-+.35+=+.15+\"
\n" ); document.write( "The sales tax got reduced by $.15
\n" ); document.write( "Hope I got it\r
\n" ); document.write( "
