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?
How much did Patrick spend on tickets? ** Patrick bought 2 tickets at $100.00 each for a total of 2*100 = $<<2*100=200.00>>200.00
How many trips did the oldest and youngest sons take? ** The oldest son went 35 times and the youngest went 15 times for a total of 35+15 = <<35+15=50>>50 trips
How much did each trip cost? ** The tickets cost $200.00 and together, the boys went to the park 50 times so each trip cost 200/50 = $<<200/50=4.00>>4.00
