When a customer takes one or more cars in for repair or service, one service ticket is written for each car. The car dealership maintains a service history for each of the cars serviced. The service records are referenced by the car’s serial number. A car brought in for service can be worked on by many mechanics, and each mechanic may work on many cars. A car that is…Computer Science Make screenshot of your answers form the programs you are using 1. Use Argo UML to draw the following: a.

Every morning, the store manager prints a report that lists overdue videos. If a video is two or more days overdue, the manager calls the customer to remind them to return the video. If a video is returned in damaged condition, the manager removes it from the video…
