You and your friends rented a cabin for May 24th. The total cost of the rental was $850. The day you are leaving, another friend calls and wants to come too. This will reduce the cost by $20 / person. Set up an equation you could use to find the original number of friends who were renting the cabin.
What is "850/(x+1) = (850/x) - 20x"
