A deposit of $10,000 at 9.5% for 90 days = _____.

I = 10,000 * 0.095 * 0.25

$237.50

To calculate the total amount of interest earned on a deposit, you can use the formula:

Interest = (Principal * Rate * Time) / 365

Where:
Principal = $10,000
Rate = 9.5% (or 0.095 as a decimal)
Time = 90 days

Now let's substitute the values into the formula:

Interest = (10,000 * 0.095 * 90) / 365

Next, calculate the final amount:

Total Amount = Principal + Interest

Let's calculate the interest first:

Interest = (10,000 * 0.095 * 90) / 365
Interest = 237.67 (rounded to the nearest cent)

Now, add the interest to the principal:

Total Amount = 10,000 + 237.67
Total Amount = $10,237.67

Therefore, a deposit of $10,000 at an interest rate of 9.5% for 90 days will yield a total amount of $10,237.67.
