Consider an airport screening security which has $3$ steps.First step, Verifying ID and boarding pass, takes $30$ Seconds per passengerSecond step, Searching the passenger for metal objects using metal detector, takes $10$ seconds per passenger.The third step, running the carry$-$on luggage through an X$-$ray machine, takes $60$ seconds per passenger.Assume that there are many customers waiting in the process and that each of the $3$ employees gets paid $$15$ per hour. $1.$ What is the cost of direct labor?$2.$ What is the labor Content?$3.$ What is the average labor utilization? A machine line has $6$ stations with processing times of $30,20,25,28,22$ and $24$ seconds per unit. The process is capacity constraint and runs on $30$ second$/$ unit cycle time$\mathrm{.}1.$ What is the average labor utilization$2.$ What is the total idle time across all six stations
