Tanner needs repairs for his truck. He can take it to Gary’s Garage for a service charge of $40 plus $30 per hour. He can also take it to Casey’s Car House for a service charge of $60 plus $20 an hour. At how many hours would it cost Tanner the same amount to take his truck to either garage? How much would he pay at this number of hours?

Answer:

Step-by-step explanation:

G=30t+40, C=20t+60, C=G

30t+40=20t+60, subtract 40 from each side

30t=20t+20, subtract 20t from each side

10t=20, divide each side by 10

t=2

So both garages charge the same fot two hours of work.
