Your family plans to take

Question

your family plans to take a vacation this summer. For the cost of the vacation to be manageable, you determine that it will be best to share a vacation home with other families. The cost ‘c’ (in dollars) per family of the vacation home is inversely proportional to the number of ‘t families’ sharing the house. Your family wants the cost of the house per family to be $600. Currently, with three families (including your family) the vacation rental cost is $1,000 per family. How many more families have to join to get the vacation home to be manageable for your family?

Answer 1

600 = 1000/3t

1800t = 1000

t = 1.8

 

Well, it's possible to have 4/5 of a family, but since an individual doesn't affect the price, you need 2 more familes.
