Average grade of 90 for 3 exams means his total score must be 270, for (270/3)=90\r
\n" ); document.write( "\n" ); document.write( "He got a 96 and an 80. They add to 176\r
\n" ); document.write( "\n" ); document.write( "270 (what he needs)- 176=94.\r
\n" ); document.write( "\n" ); document.write( "If he gets a 94, a 96, and a 80, he gets 270. \r
\n" ); document.write( "\n" ); document.write( "Another way is he was +6 on the first exam and -10 on the second. He is down 4. He needs to be +4 on the third, and that is a 94.
\n" ); document.write( "
