The Blue Mountain High School Drama Club is selling tickets to their spring musical. Adult tickets are $4 and student tickets are $1. A total of 285 tickets are sold for $765. How many of each type of ticket are sold?
\n" ); document.write( "
\n" ); document.write( "-------
\n" ); document.write( "a + s = 285 tickets
\n" ); document.write( "4a + 1s = 765
\n" ); document.write( "----
\n" ); document.write( "Multiply thru the 1st equation by 4:
\n" ); document.write( "4a + 4s = 4*285
\n" ); document.write( "4a + s = 765
\n" ); document.write( "------
\n" ); document.write( "Subtract and solve for \"s\":
\n" ); document.write( "3s = 375
\n" ); document.write( "s = 125 (# of student tickets sold)
\n" ); document.write( "---
\n" ); document.write( "Solve for a:
\n" ); document.write( "a + s = 285
\n" ); document.write( "a = 160 (# of adult tickets sold)
\n" ); document.write( "=====================
