Information $to$ solve:

Customers must schedule appointments with Mary $to$ have their cars serviced. Mary schedules the appropriate amount $of$ time needed, based $on$ the customer$s$ request for a specific service $(e.g.,brake$ repair, oil change, radiator replacement$).$

When the customer arrives, a mechanic receives the order from Mary and begins work $to$ fill the request. The mechanics record any inventory used during the service $(e.g.,oil$ filter, brake pads, radiator$)tobe$ added $to$ the customer$s$ invoice. Once the work $is$ complete, Mary receives the updated sales order from the mechanic, creates $an$ invoice for the customer, and collects payment.

Mike$s$ Auto Shop requires customers $to$ pay $at$ least $50percentof$ the cost $at$ the time $of$ a visit, but they allow customers $to$ pay off the remaining balance within $30days.$ Some customers pay the entire balance $up$ front, but others pay $50percent$ now and $50percentat$ the end $of$ the month. Mike$s$ accepts cash, checks, and Visa $or$ MasterCard.

When a mechanic notices that the shop needs $to$ order new parts $or$ other inventory items, $he$ sends a purchase requisition $to$ Mary. She fills out a purchase order and sends $itto$ one $of$ three approved vendors. The vendors ship items $as$ they are available, $soitis$ possible for a single order $tobe$ spread across multiple shipments. The vendor does not, however, combine multiple orders $in$ a single shipment.

Each $of$ the approved vendors has agreed $to$ allow Mike$s$ Auto Shop $to$ carry a monthly balance. $Mikes$ Auto receives a monthly statement each month from the three vendors, and Mary submits payment $in$ full each month $to$ pay off the balances.
