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? Identify the
operations needed to solve this problem using the equation 36x - 19 = 53.
A. addition and division
B. addition and multiplication
C. subtraction and division
D. subtraction and multiplication
The correct answer is C. subtraction and division.
The equation 36x - 19 = 53 can be solved by subtracting 19 from both sides: 36x - 19 - 19 = 53 - 19, which simplifies to 36x = 34.
Then, we divide both sides of the equation by 36 to solve for x: x = 34/36.
This gives us the number of tickets Stacia bought.
