Final answer:
22 out of 25 students earned Renaissance class participation, hence 22 students are expected to attend the Renaissance celebration.
Step-by-step explanation:
If 22 out of 25 students earned Renaissance class participation, then it is expected that 22 students will be attending the Renaissance celebration. When a question specifies the number of individuals who have achieved a particular milestone or qualification, such as earning Renaissance participation, that number directly reflects those eligible or expected to engage in related activities, such as attending a celebration meant for those who achieved that status.
