A school Tours is taking a group of 32 students and 6 adults on a tour of historical sites in the city. Each School Tours van will hold 9 passengers. What is the least number of vans that are needed to take all of the students and adults? My answer is 4?

Each student in Mr. Johns class donated $15 to a charity. There are 25 students in a class. Which expression could have been used to calculate the total amount donated?

Is it 5?

Thanks

I only guess that there should be using perentethes. But have don't get it where to use them in this problem
