A family of 4 spent $78 at the exhibition. They spent $22 on rides and the rest on entrance fees. How much was the entrance fee per person

We need to find the entrance fee per person. So subtract the cost of rides from the total spend:
Entrance Fees = Total Spend - Cost of Rides
Entrance Fees = 78 - 22
Entrance Fees = 56

Now find the entrance fee per person:
Entrance Fee Per Person = Entrance Fees / Total People in the Family
Entrance Fee Per Person =56/4
Entrance Fee Per Person = 14
