The cost per person to rent a mountain cabin is inversely proportional (varies inversely) to the number of people who share the rent. If the cost is $36 per person when 5 people share, what is the cost per person when 8 people share?
First things first, we have to find the number of people who share a room when there is 5 people to find how much the room would cost. First multiply 36 by 5. 36 x 5 = 180 Now that we know that the total amount of the room costs 180 we need to divide that by 8 to see how much each person would end up paying if 8 people shared a room. 180 / 8 = 22.50 So the amount each person would pay is $22.50 if 8 people shared a room.
