Madeline sold 200 tickets for a charter flight to Dallas. Some paid $200 for their tickets and some paid $250. Madeline's revenue for the flight was $44,000. Below is Madeline's work in determining how
many of each ticket was sold.
x = number of $200 tickets
y = number of $250 tickets
200 (200 - 1) + 250y = 44,000
40.000 - + 250y = 44.000
40.000 + 249 y = 44.000
249v = 4.000
200x + 250y = 44.000
X = 200)
y' = 16.1

As Madeline was writing "y = 16.1," she realized her answer was not correct. How did
she know?
