Students are going through a three-step process to obtain their ID cards. Each student will first visit the only registration desk before going to one of three cashiers to pay a fee for the card. After that, he/she will visit one of four ID processing stations to have his/her picture taken and the ID card printed. Registration takes 2 minutes. Visits to the cashier and ID processing station take 10 and 20 minutes, respectively. If the bottleneck resource has the utilization of 0.75(i.e., % busy), what is the flow rate through the process?
