The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 63 students, requires 7 ​chaperones, and costs ​$1,000 to rent. Each van can transport 7 ​students, requires 1​ chaperone, and costs ​$120 to rent. Since there are 630 students in the senior class that may be eligible to go on the​ trip, the officers must plan to accommodate at least 630 students. Since only 84 parents have volunteered to serve as​ chaperones, the officers must plan to use at most 84 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation​ costs? What are the minimal transportation​ costs?
