A service station charges $40 per hour for labor plus the cost of parts to repair a car. Parts can either be ordered from the car dealership for $250 or from a warehouse for $200. The equations below give the total repair cost C (in dollars) for a repair that takes t hours using parts from the dealership or from the warehouse.

Answer:1. Total charges at the service station if he gets the parts from the car dealership:C=40 t+2502. Total charges at the service station if he gets the parts from the warehouse:C=40 t+200Step-by-step explanation:1. The Total charges at the service station when at the dealership can be expressed as;Total charges at the service station(dealership)=Cost of parts at the dealership+(labor charges per hour×number of hours of service (t))where;Cost of parts at the dealership=$250Labor charges per hour×number of hours of service (t)=(40×t)=40 tTotal charges at the service station(C)=250+40 tTotal charges at the service station if he gets the parts from the car dealership:C=40 t+2502. The Total charges at the service station when at the warehouse can be expressed as;Total charges at the service station(warehouse)=Cost of parts at the warehouse+(labor charges per hour×number of hours of service (t))where;Cost of parts at the dealership=$200Labor charges per hour×number of hours of service (t)=(40×t)=40 tTotal charges at the service station(C)=200+40 tTotal charges at the service station if he gets the parts from the warehouse:C=40 t+200
