Algebra.Com's Answer #827521 by Theo(13342)![]() ![]() You can put this solution on YOUR website! i get the following. \n" ); document.write( "p = purchase price. \n" ); document.write( "c = original change \n" ); document.write( "c-1 = correct change \n" ); document.write( "since p = 2 * the original change, then p = 2c \n" ); document.write( "20 dollars was used to pay for the purchase price. \n" ); document.write( "20 minus the purchase price equals the change. \n" ); document.write( "therefore: \n" ); document.write( "c = 20 - p \n" ); document.write( "since p = 2c, you get: \n" ); document.write( "c = 20 - 2c \n" ); document.write( "solve for c to get: \n" ); document.write( "c = 20/3 \n" ); document.write( "that's the original change. \n" ); document.write( "the corrected change is c - 1 = 20/3 - 3/3 = 17/3. \n" ); document.write( "you were asked what the value of c was. \n" ); document.write( "that's the original change. \n" ); document.write( "your solution is that the original change = c = 20/3 = 6.67 rounded to the nearest penny. \n" ); document.write( "to confirm 6.67 as the original change equal to c, i did the following: \n" ); document.write( "the purchase price was 14.33. \n" ); document.write( "the original change was 6.67 \n" ); document.write( "20 - 6.67 = 13.3 \n" ); document.write( "that's 1 dollar short of the purchase price. \n" ); document.write( "to correct, 1 dollar was given back. \n" ); document.write( "that made the purchase price equal to 20 - 5.67 = 14.33, correcting the mistake. \n" ); document.write( "let me know if you have any questions. \n" ); document.write( "theo \n" ); document.write( " |
