The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 56 students, requires 4 chaperones, and costs
51,200 to rent. Each van can transport 7 students, requires 1 chaperone, and costs $110 to rent. Since there are 504 students in the senior class that may be eligible
go on the trip, the officers must plan to accommodate at least 504 students. Since only 52 parents have volunteered to serve as chaperones, the officers must plan to
use at most 52 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation
costs?
