There are 3 new seats in each row in a school auditorioum. there are 15 rows in the auditorioum. each new seat costs $74.what is the cost for the new seats?

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$

3 times 15 is 45
45 times 74 is $3,330

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !
