Alright, so you know there are 3 new seats added per row. So first, figure out the cost per row. 74 times 3 will get you 222, meaning it will be 222 dollars for each row. Now you know that there will be 15 rows, so you will multiply 222 to 15. The answer you get is 3330. So the total price for the seats is $3330.

3 new seats per row, 15 rows.
3*15=45
45 new seats.
1 seat costs 74$.
74*45=3330

The total cost of the seats is 3330$
