To calculate the annual rate on $525 at a daily rate of 0.046% for 3 months, we need to convert the daily rate to an annual rate.
First, let's calculate the interest earned over 3 months.
The daily rate is 0.046%, which is equivalent to 0.00046 in decimal form.
To calculate the interest earned over 3 months, we multiply the daily rate by the number of days in 3 months. Assuming there are 30 days in a month, the number of days in 3 months is 90.
Interest earned over 3 months = $525 * 0.00046 * 90 = $21.105
Now, let's calculate the annual rate.
To convert the interest earned over 3 months to an annual rate, we divide it by the principal amount and multiply by 100.
Annual rate = (Interest earned over 3 months / Principal amount) * 100 = ($21.105 / $525) * 100 = 4.02%
Therefore, the annual rate on $525 at a daily rate of 0.046% for 3 months is approximately 4.02%.
