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,

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
