The manager of a movie theater found that Saturday's sales were $3675. He knew that a total of 650 tickets were sold Saturday. Adult tickets cost $7.50 and children's tickets cost $4.50. Write equations to represent the number of tickets sold and the amount of money collected. How many of each kind of ticket were sold?
\n" ); document.write( "---------------------------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq:::: a + c = 650
\n" ); document.write( "Value Equation:7.5a + 4.5c = 3675
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Multiply thru 1st equation by 75:
\n" ); document.write( "Multiply thru 2nd equation by 10:
\n" ); document.write( "----------------------------
\n" ); document.write( "75a + 75c = 75*650
\n" ); document.write( "75a + 45c = 36750
\n" ); document.write( "---------------------------------
\n" ); document.write( "Subtract 2nd from 1st and solve for \"c\":
\n" ); document.write( "30c = 12000
\n" ); document.write( "c = 400 (# of children's tickets sold)
\n" ); document.write( "-----------------------
\n" ); document.write( "Since a+c = 650
\n" ); document.write( "a = 250 (# of adult tickets sold)
\n" ); document.write( "========================================
