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

nounSTATISTICS
a quantity calculated to indicate the extent of deviation for a group as a whole.
A "solution" would be a set of three numbers ... for Q, a, and c ... that
would make the equation a true statement.
If you only have one equation, then there are an infinite number of triplets
that could do it. For example, with the single equation in this question,
(Q, a, c) could be (13, 1, 2) and they could also be (16, 2, 1).
There are infinite possibilities with one equation.
In order to have a unique solution ... three definite numbers for Q, a, and c ...
you would need three equations.
