To determine which input would display “Full price ticket” from the flowchart description, we need to analyze the conditions outlined.
- First, the flowchart asks for "Input Age".
- Then it checks if the age is 16 or under.
- If Yes, it leads to “Half-price ticket”.
- If No, it checks if the age is 60 or above.
- For the second check:
- If Yes (age 60 or above), it leads to “Half-price ticket”.
- If No (age below 60), it leads to “Full price ticket”.
From this, we can deduce that to display “Full price ticket,” the input age must be below 16 and below 60. The only age range that would reach the “Full price ticket” condition is any age that is more than 16 and less than 60.
Among the options given:
- 65: This would result in “Half-price ticket” because it is above 60.
- 15: This would lead to "Half-price ticket" because it is 16 or under.
- 20: This is between 16 and 60 and would result in “Full price ticket”.
- 60: This would result in “Half-price ticket” because it is 60 or above.
Therefore, the input that would display "Full price ticket" is:
20
