This coming summer, we are meeting up with some family members at Family Fiesta Amusement Park. The ticket price for children is $17 and for adults the ticket price is $31. The total price for all 20 of us to enter the park is $438.
\n" ); document.write( "----
\n" ); document.write( "People Eq.::: a + c = 20
\n" ); document.write( "Value Eq.:: 31a+17c = 438
\n" ); document.write( "----
\n" ); document.write( "Multiply thru People Eq. by 31 to get:
\n" ); document.write( "31a + 31c = 31*20
\n" ); document.write( "----
\n" ); document.write( "Subtract from the Value Eq and solve for \"c\":
\n" ); document.write( "-14c = 438-31*20
\n" ); document.write( "-14c = -182
\n" ); document.write( "---
\n" ); document.write( "c = 13 (# of child tickets sold)
\n" ); document.write( "---
\n" ); document.write( "Since a + c = 20, a = 7 (# of adult tickets sold)
