Adult tickets for a play cost $18 and child tickets cost $2. If there were 20 people at a performance and the theater collected $88 from ticket sales, how many children attended the play?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Lex x: number of children who attended the play
\n" ); document.write( " 20-x: number of adults who attended the play\r
\n" ); document.write( "\n" ); document.write( "Adult tickets: $18
\n" ); document.write( "Child tickets: $2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equation:
\n" ); document.write( "2x + 18(20-x) = 88\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solution:
\n" ); document.write( "2x + 360 - 18x = 88
\n" ); document.write( "-16x + 360 = 88
\n" ); document.write( "-16x = 88 - 360
\n" ); document.write( "-16x = -272\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by -16.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer:
\n" ); document.write( "x = -272/-16
\n" ); document.write( "x = 17
\n" ); document.write( "17 children attended the play.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "2(17) + 18(20-17) = 88
\n" ); document.write( "2(17) + 18(3) = 88
\n" ); document.write( "34 + 54 = 88
\n" ); document.write( "88 = 88 (true)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 17 children\r
\n" ); document.write( "
