1. Total charges at the service station if he gets the parts from the car dealership:C=40 t+250

2. Total charges at the service station if he gets the parts from the warehouse:C=40 t+200

Step-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=$250

Labor charges per hour*number of hours of service (t) = (40*t) = 40 t

Total charges at the service station (C) = 250+40 t

Total charges at the service station if he gets the parts from the car dealership:C=40 t+250

2. 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=$200

Labor charges per hour*number of hours of service (t) = (40*t) = 40 t

Total charges at the service station (C) = 200+40 t

Total charges at the service station if he gets the parts from the warehouse:C=40 t+200
