Question 384267: Hello, I need some help with a word problem:
A drama club is planning a bus trip to NYC to see a Broadway play. The cost per person for the bus rental varies inversely as the number of people going on the trip. It will cost $31 per person if 50 people go on the trip. How much will it cost per person if 81 people go on the trip?
Thanks for the help!

A drama club is planning a bus trip to NYC to see a Broadway play. The cost per person for the bus rental varies inversely as the number of people going on the trip.
---
c = k/n
--------------
Solve for "k":
It will cost $31 per person if 50 people go on the trip.
31 = k/50
k = 1550
---
How much will it cost per person if 81 people go on the trip?
c(n) = 1550/n
------
c(81) = 1550/81
-----
c(81) = $19.14
