1 batang = 2.000
1 lusin = 12 batang
12 x 2.000 = 24.000

║Subject : Linear equations of one variable║
║Grade : VII of Junior High School║
Known :
⇒ 1 dozen = 20.000 ( Buying )
⇒ 2.000 = 1 stem ( selling )
Asked for :
⇒ % of the profit ?
≡ First , we count the income of the selling !
⇒ 2.000 × 12
⇒ 24.000
as we know , in 1 dozen there's 12 thing !
≡ Second , we count the profit !
⇒ 24.000 - 20.000
⇒ 4.000
≡ Finally , count the percent of the profit !
⇒ (4.000 / 20.000) × 100%
⇒ 20%
