The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 80 students, requires 5

chaperones, and costs $1,400 to rent. Each van can transport 10 students requires 1 chaperone, and costs $100 to rent. Since there are 800 students

in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 800 students. Since only 65 parents have

volunteered to serve as chaperones, the officers must plan to use at most 65 chaperones. How many vehicles of each type should the officers rent in

order to minimize the transportation costs? What are the minimal transportation costs?
