What is the cash fare for regular full fare for students aged 12-20?

The correct cash fare for regular full fare for students aged 12-20 is $2.50. This fare reflects the standard pricing structure that the Chicago Transit Authority (CTA) has established for student riders, which is often set below the regular adult fare to make public transportation more accessible for younger riders.

Setting the fare at $2.50 provides an equitable option for students who may be on a limited budget while also encouraging the use of public transit for educational and extracurricular activities. The fare is structured to maintain a balance between sustainability for the transit system and accessibility for students.

Returning to other options, they do not align with the established fare for students within this age range, which further reinforces the necessity of the correct fare in ensuring that CTA services remain affordable for educational purposes.
