They expect to sell all 850 tickets, some at $12 and the rest at $8.
\n" ); document.write( "---
\n" ); document.write( "Quantity Eq: t + e = 850 tickets
\n" ); document.write( "---
\n" ); document.write( "The group require the ticket sales to cover their $3760 production costs and to make a profit of $4000.
\n" ); document.write( "Value Equation: 12t + 8e = 7760 dollars
\n" ); document.write( "-----------------------\r
\n" ); document.write( "\n" ); document.write( "If they are to exactly achieve this target and their expectations regarding ticket sales are correct how many of the 850 tickets should they charge $12 for and how many should they charge $8 for?
\n" ); document.write( "----
\n" ); document.write( "Multiply thru the Quantity Eq. by 12:
\n" ); document.write( "12t + 12e = 12*850
\n" ); document.write( "12t + 8e = 7760
\n" ); document.write( "----
\n" ); document.write( "Subtract to get:
\n" ); document.write( "4e = 2440
\n" ); document.write( "e = 610 (# of $8 tickets needed)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"t\":
\n" ); document.write( "t + e = 850
\n" ); document.write( "t + 610 = 850
\n" ); document.write( "t = 240 (# of $12 tickets needed)
\n" ); document.write( "=================================
