Answer 1

Okay, here we have this:

Inicially we have 5000 students, let's calculate how many were left in 2019:

Students in 2019=5000*0.9

Students in 2019=4500

Now, let's finally calculate how many were left in 2020:

Students in 2020=4500*0.95

Students in 2020=4275

Finally in 2020 they were 4275 students
