A school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second grade travel in the bus. How many ways can the students be seated if all of the second-grade students occupy the first row?

thats a trick question because, if the second graders occupy the first row, it leaves 4 rows left. So all the first graders can sit in the 4 rows behind the second graders. Am i right?
