One summer evening 1600 concert tickets were sold for the Fairmont Summer Jazz Festival. Tickets cost $25 for covered pavilion seats and $15 for lawn seats. Total receipts were $34,000. How many lawn and pavilion seats were sold?
----------------------------------------------------------------------
Let x be the number of tickets sold for covered pavilion.
Then the number of tickets sold for lawn seats is 1600-x.
The balance equation is
25x + 15*(1600-x) = 34000.
Simplify and solve:
25x + 24000 - 15x = 34000,
10x = 34000 - 24000,
10x = 10000,
x = = 1000.
Answer. 1000 tickets for pavilion and 1600-1000 = 600 tickets for lawn seats were sold.
