If i wanted to go on a trip, i have to pass class with an 82.5%. I had 71% last semester . What would i have to get this semester? they take the average of both semesters.
\n" ); document.write( ":
\n" ); document.write( "Let x = grade required in the 2nd semester to get 82.5 average of the year
\n" ); document.write( " $\"%2871%2Bx%29%2F2\"$ = 82.5
\n" ); document.write( "Multiply both sides by 2
\n" ); document.write( "71 + x = 165
\n" ); document.write( "x = 165 - 71
\n" ); document.write( "x = 94% and you pack your bags for the trip \n" ); document.write( "

\n" );
