Lizzy: Patrick buys a season pass for each of his sons to visit the local amusement park as often as they want. The passes were $100.00 each. The oldest son went to the park 35 times over the summer and the youngest went 15 times. What was the cost per trip to the park?.
Me: Hmmm, let me think. I think this is the detailed solution:
Patrick bought 2 tickets at $100.00 each for a total of 2 * 100 = $200.00. The oldest son went 35 times and the youngest went 15 times for a total of 35 + 15 = 50 trips. The tickets cost $200.00 and together, the boys went to the park 50 times so each trip cost 200 / 50 = $4.00. Final answer: 4.
