11. Word Problem! Oh No! Your car has broken down! You don't like walking so you call the local garage to find out what they will charge you to fix it. The mechanic tells you that they charge a flat fee of $100 to use the diagnostic computer to find the trouble plus $30 per hour for labor. a) Write a linear equation that will predict the cost of repairing your car. b) Use the equation to find out how much you will have to pay if the repairs take 6 hours.
