Let x be the number of people going on the trip and y be the cost per person.
We know that the cost per person varies inversely as the number of people, so we have the equation:
xy = k
where k is a constant.
We are given that it will cost $30 per person if 44 people go on the trip:
30(44) = k
k = 1320
Now we can plug in the values for k and x to find the cost per person if 20 people go on the trip:
20y = 1320
y = 1320/20
y = $66
Therefore, if 20 people go on the trip, it will cost $66 per person.
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 as 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 20 people go on the trip? Round your answer to the nearest cent, if necessary.
