It takes the ostrich 18 minutes to run 15 miles.
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
-2 x -47 = 94
Negative 2 multiplied by negative 47 equals 94
