Final answer:
15 advance tickets and 35 same-day tickets were sold for the show.
Step-by-step explanation:
Let's assume that the number of advance tickets sold is x.
Since there were 50 tickets sold in total, the number of same-day tickets sold would be 50 - x.
The total amount paid for advance tickets would be 30x and the total amount paid for same-day tickets would be 15(50 - x).
According to the information given in the question, the total amount paid for all the tickets was $975.
So we can write the equation:
30x + 15(50 - x) = 975
Now we can solve this equation to find the value of x, which represents the number of advance tickets sold.
Expanding the equation, we have:
30x + 750 - 15x = 975
Combining like terms, we get:
15x + 750 = 975
Subtracting 750 from both sides, we get:
15x = 225
Dividing both sides by 15, we get:
x = 15
Therefore, 15 advance tickets were sold and 35 same-day tickets were sold.
