Answer:
45×7
Step-by-step explanation:
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row
now use a sum sequence to find total number of seats
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 total seats

Does the answer help you?
Leave the whole number alone for now. Divide 41 by 80 and you get 0.5125
So your answer is 9.5125
