Class 12 Study Trip: Cost Information

Class 12 will visit a science museum and a factory. The trip is open to all students. The costs are shown below.

Item	Cost
Bus (rental, one bus for up to 40 students)	Rp2.400.000 per bus
Museum ticket	Rp25.000 per student
Factory tour	Rp15.000 per student
Lunch box	Rp20.000 per student

The costs are shared equally among the participating students. Teachers travel free, and the school will pay for the lunch of teachers. If more than 40 students join, a second bus must be rented. Registration closes on Friday. Students who register after the deadline must pay an extra Rp10.000.

Choose ALL the numbers of participants for which the cost per student (excluding late fees) is higher than Rp120.000. (More than one answer is correct.)
