(75% × 60 − 42) ÷ (1 − 75%), rounded up12
The formulas
Attendance = attended ÷ held × 100 · Classes needed = (r × held − attended) ÷ (1 − r) · Can miss = attended ÷ r − held

With 42 of 60 classes attended, attendance is 70%. Attending the next 12 in a row brings it to 54 of 72, exactly 75%.
Questions people ask
How do I calculate attendance percentage?
Divide the classes you attended by the classes held and multiply by 100. 42 of 60 is 70%.
How many classes do I need to reach 75%?
Attend the next (75% × classes held − attended) ÷ 25% classes without missing any. From 42 of 60, that's 12 classes: 54 of 72 is 75%.
How many classes can I miss?
Divide classes attended by 75% and subtract classes held, then round down. With 50 of 60, you can miss 6 and stay at 75.76%.
