From this equation C°=[F°-32]÷1.8
F°=158×1.8 +32=316.4°
Forty three million, eighty thousand and seven hundred.
First multiply 12 by 8 to get 96
that is the total amount of seats including the broken ones. then multiply 3 by 4 to get the section of broken seats. 3 being the amount of rows that have broken seats an 4 is the amount of broken seats per row. you wind up with 12 broken seats.
Now subtract 12 from 96 to get 84 functional seats
