I have 4 math test this quarter, so far I have made a 80,73, and 60. If I want to have at least an average of 78, what is the lowest grade I can make.

\n" ); document.write( "Points you have:: 80+73+60 = 213
\n" ); document.write( "Points you need:: 4*78 = 312
\n" ); document.write( "Points you need on 4th test:: 312-213 = 99
\n" ); document.write( "------
\n" ); document.write( "Let the 4th test score be x::
\n" ); document.write( "213+x = 4*78
\n" ); document.write( "x = 312-213 = 99
\n" ); document.write( "---------------
