A disk jockey must play 14 commercial slots during 1 hour of a raido show.Each commercial is either 30 seconds or 60 seconds long. If the total commercial time during a 1 hour show is 11 minutes, how many 30 second commericals and how many 60 second commercials were played? in that hour?
\n" ); document.write( "--------
\n" ); document.write( "Slot equation: t + s = 14 slots
\n" ); document.write( "Time equation:30t+60s = 11*60 seconds
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Divide thru the Time equation by 30
\n" ); document.write( "t + s = 14
\n" ); document.write( "t + 2s= 22
\n" ); document.write( "-----
\n" ); document.write( "Subtract and solve for \"s\":
\n" ); document.write( "s = 8 (# of sixty-second commercials played)
\n" ); document.write( "---
\n" ); document.write( "t + 8 = 14
\n" ); document.write( "t = 6 (# of thirty0second commercials played)
