The 9 officers of the Student Council are going on a trip to an amusement park. Each student must pay an entrance fee plus $5 for meals. The total cost of the trip is $225. Solve the equation 9(e + 5) = 225 to find the cost e of the entrance fee for each student is $20 . 9(e + 5) = 225 e + 5 = 25 e = 25 - 5 e = 20
