Final answer:
The total number of tickets sold at the concert was 435. With 50 general admission tickets sold, by subtracting these from the total, we determine that 385 student tickets were sold.
Step-by-step explanation:
The question asks us to solve for the number of student tickets sold at a BIS concert given that the total tickets sold were 435 and there were 50 general admission tickets sold. We know that the price for a general admission ticket is $150, and a student ticket costs $35. To find the number of student tickets sold, we first calculate the total number of tickets and then subtract the number of general admission tickets.
Let's define the number of student tickets as 'S'. According to the given information:
Total tickets (general admission + student tickets) = 435
General admission tickets = 50
S + 50 = 435
S = 435 - 50
S = 385
Hence, the number of student tickets sold is 385.
