The cost per person to rent a chartered bus varies inversely to the number of people who red the bus. If 40 people pay $9.50 each to ride the chartered bus, what is the cost pet person if only 25 people go?
Answer provided by our tutors
let c be the cost rson per peand c= x/n where n is number of people
c = 9.5 = x/40 => x = 40*9.5 = 380
when n = 25
c = 380/25 = 15.2
