In the present case the price of the ride is equal to the marginal social cost.

Part 1) As can be seen from the above table the total number of rides is 60 for price $90. So, the marginal social cost will be $90.

Part 2) The number of rides for each seller is following

Xavier = 25

Yasmin = 20

Zack = 15

Part 3) Marginal social cost for each firm is also $90.

Price ($ per ride)
