The marks of 7 students in a test are 88, 75, 93, 98, 27, 80, and 36.
\n" ); document.write( " If 8 students sat the test and the average mark was 65, what score did the eighth student achieve on the test?
\n" ); document.write( ":
\n" ); document.write( "let x = the score of the 8th student
\n" ); document.write( ":
\n" ); document.write( "\"%2888%2B75%2B93%2B98%2B27%2B80%2B36%2Bx%29%2F8\" = 65
\n" ); document.write( "add em up and multiply both sides by 8
\n" ); document.write( "497 + x = 520
\n" ); document.write( "x = 520 - 497
\n" ); document.write( "x = 23 is the score of the 8th student
\n" ); document.write( "
\n" );
