Cost of Renting a Truck. The cost of renting a truck is \$280 per week plus a charge of \$0.30 per mile driven. (a) Write a linear equation that relates the cost C for a weekly rental in which the truck is driven x miles. C = (b) What is the rental cost if you drive 600 miles in a week

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.
