A drama club is planning a bus trip to New York City to see a Broadway play. The cost per person for the bus rental varies inversely to the number of people going on the trip. It will cost $30 per person if 44 people go on the trip. How much will it cost per person if 55 people go on the trip? Round your answer to the nearest cent, if necessary. (1 point) Responses

Solution:
Let x be the number of people going on the trip and y be the cost per person.
From the information given, we know that the cost per person varies inversely with the number of people:
y = k/x
where k is a constant.
We can use the information that it will cost $30 per person if 44 people go on the trip to find the value of k:
30 = k/44
k = 30 * 44
k = 1320
Now we can find the cost per person if 55 people go on the trip:
y = 1320/55
y = $24.00
Therefore, it will cost $24.00 per person if 55 people go on the trip.
