Question

The German club is planning a ski trip.The club will pay $500 toward the trip, and each member going on the trip will pay $115. If the trip costs $2,685,write and solve an equation to find the number of club members going on the trip

Answer 1

500+(x115)=2685

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.
