A group of people hired a boat for 1200 dollars and each person paid an equal amount for it. Five people did not turn up, so each person on the trip had to pay 8 dollars more. Find the number of people in the group who went on the trip.
+36916 x = original # of people
1200 /x = amount each person paid
x - 5 new number of people
1200 / ( x-5) = new amount =
1200 / (x-5) = 1200/x + 8 solve for 'x'
