"and only ___ of the friends..."

To find out how much the ride pass cost, we can start by subtracting the admission costs for the six friends from the total amount spent.

The admission cost for each person is given as $8.50, and there were six friends, so the total admission cost would be 6 friends x $8.50 = $51.

Now, we can subtract the admission cost from the total amount spent: $102 - $51 = $51.

Since the rest of the amount spent ($51) represents the cost of the ride pass, we can conclude that the ride pass cost $51.
