Step-by-step explanation: To find out how many lawn seats were sold, we need to first determine the total revenue generated by selling pavilion seats.
We know that the cost of a pavilion seat is $23.50, and the number of pavilion seats sold is 655. So, the revenue from pavilion seats can be calculated by multiplying the cost per seat by the number of seats sold:
Revenue from pavilion seats = $23.50 × 655
Next, we need to find the revenue from lawn seats. The total revenue from ticket sales is given as $34,954. To find the revenue from lawn seats, we subtract the revenue from pavilion seats from the total revenue:
Revenue from lawn seats = Total revenue - Revenue from pavilion seats
Now, we can substitute the known values into the equation:
Revenue from lawn seats = $34,954 - ( $23.50 × 655 )
Calculating this equation will give us the revenue generated by selling lawn seats. Finally, we can determine the number of lawn seats sold by dividing the revenue from lawn seats by the cost per lawn seat:
Number of lawn seats sold = Revenue from lawn seats / Cost per lawn seat
By following these steps, you will be able to find the number of lawn seats sold at the outdoor concert stadium.
