jane runs 12 miles a day.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "how many miles does she run in 76 days?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12 * 80 = 960\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12 * 70 = 840\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "75 is close to 76 and halfway between 70 and 80, therefore your answer will be halfway between 840 and 960.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "960 - 840 = 120.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "half of 120 = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "add 60 to 840 to get 900\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 60 from 960 to get 900.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that would make the estimate about 900.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "another way to estimate would be 10 * 75 + 2 * 75 = 750 + 150 = 900.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
