LEARNING ACTIVITY 2

SINGLE INTEREST, DISCOUNT, AND TAX

In general, interest can be interpreted as a service in the form of
money provided by the borrower to the party who lends capital with

mutual agreement.

There are times when interest can also be interpreted as a service in
the form of money provided by the bank to the saving party with

mutual consent.

1 year interest = percent interest × capital

Interest b month = × percent interest × capital
12
= × 1 year interest
12
The percentage of interest is always stated for 1 year, unless there is other
information in the problem.

For a better understanding, let's pay attention to the following question :

Vega saves in the bank IDR 2.000.000,00- with an interest rate of 18% a year with single interest.
Define

a. The amount of interest at the end of the first month;
b. The amount of interest at the end of the sixth month;

c. The amount of money after 2 years.

Solution :

Known : Capital = IDR 2.000.000,00

Interest = 18% a year
a. Interest at the end of the first month

1 18
× × IDR 2.000.000,00 = IDR 30.000,00
12 100
