Final answer:
To find the percentage of seats on the train that are empty, divide the number of empty seats by the total number of seats and multiply by 100.
Step-by-step explanation:
To find the percentage of seats on the train that are empty, divide the number of empty seats by the total number of seats and multiply by 100.
In this case, there are 37 empty seats and a total of 50 seats (37 empty + 13 occupied). So the percentage of empty seats is:
(37 / 50) * 100 = 74%
