Question

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

Answer 1

let entrance fee per kid be x
total cost per kid including meals = x+5
total cost for 9 kids = 9(x+5)
total cost actually = 225

so, 225 = 9(x+5) --> now solve for 'x'.
