Calculate the simple interest obtained by a capital of R$1250.00 for 6 months (180 days) at a rate of 0.02% per day. The formula for calculating s...

The formula for calculating simple interest is given by:

�=���

j=P×i×n

Where:

• �
• j is the simple interest,
• �
• P is the principal amount (capital),
• �
• i is the interest rate per period, and
• �
• n is the number of periods.

In this case:

• �=�$1250.00
• P=R$1250.00 (principal amount),
• �=0.02%
• i=0.02% per day (interest rate per day), and
• �=180
• n=180 days (number of days).

First, convert the percentage interest rate to a decimal by dividing it by 100:

�=0.02100=0.0002

i=100

0.02

​=0.0002

Now, substitute the values into the formula:

�=1250×0.0002×180

j=1250×0.0002×180

Calculate:

�=1250×0.0002×180=45

j=1250×0.0002×180=45

Therefore, the simple interest obtained is �$45.00

R$45.00.
