Stacia wanted concert tickets that were selling for $36 each, and then she got a $19 discount. She paid a total of $53 for the tickets. How many tickets did she buy?
Let's start by subtracting the discount from the original price of the tickets: $36 - $19 = $<<36-19=17>>17.
Now we can divide the total amount she paid by the price per ticket to find the number of tickets: $53 / $17/ticket = <<53/17=3>>3 tickets. Answer: \boxed{3}.
