The cost per person to rent a mountain cabin is inversely proportional 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.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
