Answer :
5 servers would be needed to process 100 cups per hour during rush hour. A server would be able to process 80 cups of coffee in a single shift. 9 servers would be necessary for an 8-hour day where 720 cups of coffee are served.
To determine the number of servers needed for different scenarios, we can use the given information that one server can make and serve 20 cups of coffee per hour during a 4-hour shift.
To process 100 cups per hour during rush hour, we divide the desired cups per hour by the cups served by one server per hour:
Number of servers = 100 cups per hour / 20 cups per hour per server = 5 servers
Therefore, 5 servers would be needed to process 100 cups per hour during rush hour.
To calculate the number of cups of coffee a server can process in a single shift, we multiply the cups served per hour by the number of hours in a shift:
Cups processed by a server in a single shift = 20 cups per hour per server x 4 hours = 80 cups
A server would be able to process 80 cups of coffee in a single shift.
To determine the number of servers needed for an 8-hour day where 720 cups of coffee are served, we divide the total cups served by one server in a single shift:
Number of servers = 720 cups / 80 cups per server per shift = 9 servers
Therefore, 9 servers would be necessary for an 8-hour day where 720 cups of coffee are served.
