Final answer:
To find the percentage, divide the number of discount tickets by the total number of tickets and multiply by 100. In this case, 70% of the tickets sold were discount tickets.
Step-by-step explanation:
To find the percentage of discount tickets, divide the number of discount tickets by the total number of tickets and multiply by 100. In this case, there were 14 discount tickets out of 20 total tickets:
Percentage = (14 / 20) * 100 = 70%.
Therefore, 70% of the tickets sold were discount tickets.
