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.

2. Quiz. Solve the problems by applying
the Polya’s 4-step method.
1.A car rental charge ₱1,000
per day plus ₱5.00 per mile
traveled. If a total of 300
miles was traveled in a day,
how much will the rental
company received as
payment?

3. 2.Gian’s Store has a payphone
service charges ₱5 for the
first three minutes and ₱2 for
every minute additional or a
fraction thereof. How much
will a caller have to pay if his
call lasts for 10 minutes?

4. a. Let x = be the number of miles traveled
y = be the total payment
b. f(x) = 5x + 1000
c. If x = 300 miles
f(x) = 5x + 1000
= 5(300) + 1000
= 1500 + 1000
f(x) = ₱2500
