A promoter needs to make $77,700 from the sale of 2500 tickets. She charges $29 for some tickets and $55 for the others.
(a) If there are x of the $29 tickets sold and y of the $55 tickets sold, write an
equation that states that the sum of the tickets sold is 2500.
(b) How much money is received for the sale of x tickets for $29 each?
(c) How much money is received for the sale of y tickets for $55 each?
(d) Write an equation that states that the total amount received from the sale is
$77,700.
(e) Solve the equations simultaneously to find how many tickets of each type must
be sold to yield the $77,700.
