R * s = 273
r = s - 8.....s = r + 8
r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0
r - 13 = 0
r = 13
r + 21 = 0
r = -21.....extraneous solution...not ur answer
r = 13
s = r + 8 = 13 + 8 = 21
so there are 13 rows.....each row containing 21 seats
I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.

Answer: 3.19
Step-by-step explanation:
So to find the average I used a simple but pretty effective method
3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+8/26=3.1923
So the new average is 3.19
