This document provides two word problems involving linear functions and their solutions. The first problem involves calculating the total payment for a car rental with a daily fee of ₱1,000 plus ₱5 per mile, given 300 miles were traveled. The solution shows setting up the linear function f(x) = 5x + 1000 and calculating f(300) = ₱2,500. The second problem involves calculating the payment for a 10 minute phone call with an initial 3 minute fee of ₱5 and ₱2 for each additional minute, following the Polya's 4-step method.
