Well, you can get an idea of what the problem is asking by looking for key words. So the base cost of renting the car is $280 for one week, *plus* a charge of 30 cents per x miles. So the linear equation would be 280+.30x. To find the total cost for renting the car and driving 600 miles, simply multiply .30 by x=600.
