Answer:

let

c = the number of covered pavilion tickets sold

l = the number of lawn seats tickets sold

one evening 1400 concert tickets were sold

c + l = 1,400

total receipts were $30,000

30c + 15l = 30,000

by solving the system of equations

c + l = 1,400

30c + 15l = 30,000

we find

c = 400 covered pavilion seats

l = 1,200 lawn seats

by plugging the correct numbers into each other
