PROB 1. Data collected at a parking lot indicate that a total of
300 cars park between 8 a.m. and 6 p.m. 10% of these cars
are parked for an average of 2 hr, 30% for an average of 4 hr,
and the remaining cars are parked for an average of 10 hr.
Determine the space-hours of demand at the lot
PROB 2. If 10% of…
