If you have already taken 3 tests and scored 82, 64, and 98, then you have scored 82 + 64 + 98 = 244. That means you must score at least 280 - 244 = 36 points on the last exam.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
