A multi-storey car park has eight levels. On the top seven levels there are eight rows of parking. Two of these rows hold 15 cars each whilst the others hold 10 cars each. On the road level there are two rows holding 15 cars but only four rows holding 10 cars each. The entry control system counts cars in and out. The system stops admitting cars once 90% of the total capacity is in use. Four spaces on the road level are reserved for staff parking and these are not available to the public. What is the maximum number of public cars which can be admitted?
