Costumers in Toy Store
A local toy store is counting how many costumers are in the store over a four hour period. The owner of the store started keeping count in hours and counted each costumer by one. When the store opens, zero costumers are in the store. Costumers increase coming in the store at a fast rate, so at the first hour twenty costumers are in the store, which is the highest point. From the time between the first hour and second hour, the number of costumers decreases at little slower rate than the time the number of costumers increased. At the second hour, there was ten costumers. For the last two hours, the store has a constant rate of ten costumers. The owner wanted the last ten costumers to stay for a fun raffle, so there was a constant rate of the last 10 costumers.
