Alrighty! KFC! Keep, change, flip! When dividing fractions, you keep the first fraction, flip the second, and change the divide sign to multiply. Here is work as requested.
the 500 is the money the club is putting towards the trip. the x is the number of club members. the 115 is the cost each member will pay to go on the trip.
subtract 500 from each side leaving you with (x115)=2185 divide each side by 115 x=19 there are 19 club members going on the trip.
