Assuming each test is worth the same, there are a possible 400 points. So far she has 84+55+76 = 215.
\n" ); document.write( "She desires 70% of 400, or a minimum of 280 points.
\n" ); document.write( "280 points - 215 already earned = 65 points minimum on her next exam.

\n" ); document.write( "She should aim higher ;-)
