Exact Interest
1. **State the problem:** Calculate the exact interest on 65250 at 9.5% interest rate from March 12, 2020, to September 15, 2020, using approximate time.
2. **Calculate the time period:**
- From March 12 to September 15 is 6 months and 3 days.
- Approximate time counts each month as 30 days, so total days = 6 \times 30 + 3 = 180 + 3 = 183 days.
- Convert days to years: $$\text{Time} = \frac{183}{360} = 0.5083 \text{ years}$$
3. **Use the simple interest formula:**
$$\text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time}$$
- Principal = 65250
- Rate = 9.5% = 0.095
- Time = 0.5083 years
4. **Calculate the interest:**
$$\text{Interest} = 65250 \times 0.095 \times 0.5083 = 3150.23$$
5. **Final answer:**
The exact interest using approximate time is **3150.23**.
