Algebra.Com's Answer #484165 by KMST(5328)![]() ![]() You can put this solution on YOUR website! They probably mean that the buyer pays $100 including the 7.24% tax. \n" ); document.write( "That would mean that the buyer pays 107.25% of the price of the painting, \n" ); document.write( "with the seller getting 100% of the price of the painting, \n" ); document.write( "and the state getting 7.25% of the price of the painting. \n" ); document.write( " \n" ); document.write( "7.25% as a ratio and as a decimal is \n" ); document.write( "107.25% as a ratio and as a decimal is \n" ); document.write( "The price times \n" ); document.write( "The price was \n" ); document.write( "$100 ÷ 1.0725 = $93.24, \n" ); document.write( "and that is what the seller gets. \n" ); document.write( "The state gets the remaining \n" ); document.write( "( $100 - $93.24 = $6.76 ), \n" ); document.write( "which is 7.25% of $93.24. \n" ); document.write( " \n" ); document.write( "We can verify by calculating 7.25% of $93.24 \n" ); document.write( "$93.24 times 0.0725 = $6.76 \n" ); document.write( " \n" ); document.write( "NOTES: \n" ); document.write( "I get $6.76 after rounding the 6.7599 result, \n" ); document.write( "but I also had to round the result of 100 ÷ 1.0725, \n" ); document.write( "which was 93.24009324009324009324009234........ \n" ); document.write( "It was very clever of the seller to calculate the price as $93.24, \n" ); document.write( "so that the total payment, with tax, would add up to an even $100. \n" ); document.write( "That even $100 is very convenient for the buyer, \n" ); document.write( "who probably does not know even know that the seller does not get to keep the whole $100. \n" ); document.write( " |
