This document provides a detailed example of calculating the rental costs for trucks, using two different pricing structures. For the Triad Truck Rental Company, we illustrate how to determine the total costs for a one-day trip covering 340 miles. The cost formula integrates a daily rate and a per-mile fee. Additionally, we analyze another rental scenario with fees for a three-day rental and mileage restrictions. These calculations demonstrate the application of linear functions in real-world rental scenarios and help establish budgeting for truck rentals.

The Triad Truck Rental Company charges $35 per day plus $0.21 per mile. Find the cost of renting a truck for a one day trip of 340 miles? M=$ 0.21 per mile B= $35 f(x) = 0.21 x +35 f(340) = 0.21 (340) +35 f(340) = $106. 40
