Let the grades on the 4th and 5th tests = \"a\" and \"b\"
\n" ); document.write( "The problem wants to know what is \"%28a+%2B+b%29%2F2\"
\n" ); document.write( "given:
\n" ); document.write( "\"%2891+%2B+87+%2B+86+%2B+a+%2B+b%29%2F5+=+95\"
\n" ); document.write( "\"264+%2B+a+%2B+b+=+5%2A95\"
\n" ); document.write( "\"a+%2B+b+=+475+-+264\"
\n" ); document.write( "\"a+%2B+b+=+211\"
\n" ); document.write( "\"%28a+%2B+b%29%2F2+=+105.5\"
\n" ); document.write( "It looks like you can't average 95% for the 5 tests, because
\n" ); document.write( "then you would need to get better than 100% on the 4th and 5th tests
\n" ); document.write( "
