document.write( "Question 1164369: Sandy had some apples and Pears. After selling 1/3 of the apples and 7 pears, the number of pears left was a quarter of the number of apples left. If the number of pears sold was 1/6 the number of the pears that were not sold, how many pears did Sandy have at first?? \n" ); document.write( "
Algebra.Com's Answer #788754 by Theo(13342)![]() ![]() You can put this solution on YOUR website! sandy had x apples and y pears. \n" ); document.write( "x = number of apples. \n" ); document.write( "y = number of pears.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "she sold 1/3 * x apples and 7 pears. \n" ); document.write( "she had 2/3 * x apples and y - 7 pears left.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the number of pears that were left was 1/4 of the number of apples that were left. \n" ); document.write( "y - 7 = 1/4 * 2/3 * x = 1/6 * x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the number of pears sold was 1/6 * the number of pears that were not sold. \n" ); document.write( "7 = 1/6 * 1/6 * x = 1/36 * x \n" ); document.write( "solve for x to get x = 7 * 36 = 252. \n" ); document.write( "you have: \n" ); document.write( "x = 252\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since the number of pears that were not sold is equal to 1/6 * x, then the number of pears not sold is equal to 1/6 * 252 = 42 \n" ); document.write( "you have y - 7 = 42 \n" ); document.write( "solve for y to get y = 42 + 7 = 49 \n" ); document.write( "you have: \n" ); document.write( "y = 49\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 252 and y = 49 means she had 252 apples at first and 49 pears at first.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "to confirm, go through the problem again with 252 apples and 49 pears. \n" ); document.write( "she sold 1/3 of the apples and 7 of the pears. \n" ); document.write( "that means she sold 84 apples and 7 pears. \n" ); document.write( "252 - 84 = 168 apples left. \n" ); document.write( "49 - 2 = 42 pears left. \n" ); document.write( "the number of pears left was 1/4 of the number of apples left. \n" ); document.write( "42 = 1/4 * 168 becomes 42 = 42, confirming this is correct. \n" ); document.write( "the number of pears sold was 1/6 times the number of pears that were not sold. \n" ); document.write( "7 pears were sold. \n" ); document.write( "1/6 * 42 = 7, confirming this is correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the solution looks good. \n" ); document.write( "the solution is that she had 49 pears at first.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
