2.    Presentation of the Lesson
Let’s see some of the buyer’s problem while they are on a store.
a . A shirt worth 600 php is on sale at 360 php. What percent is the shirt on sale?
Ask:
·         What is asked in the problem?
(The percent of the shirt on sale.)
·         What are the given information or data that can help us solve the problem?
(original price= 600 php ; discounted price= 360 php)
·         What is the formula to be used?
(R=P/B x 100)
·         What is the solution on the given equation?
R = 360 / 600
 R = 0.6 x 100
 R = 60 %
( The shirt was 60 % on sale)

b.    In a department store, 60% of the employees are men. If there are 27 men in the store, how many employees are there all?

( rate of men  = 60 % ; total number of men = 27)
·         What is the formula to be used?
( B= P/R)
·         What is the solution on the given equation?
B= P/R
B= 27 / 0.60
B= 45
( The total number of employees is 45)

c.    During the Book Week, 20 % of the 50 students of Miss Lopez went to Maliwanag Bookstore. How many students went to the Bookstore?
