5.  Find the present value of P115,000 due in 200 days at”
a. 15% discount rate.
b. 15% simple interest.

To solve for the present value of P115,000 due in 200 days at a 15% discount rate and a 15% simple interest rate, we need to use the appropriate formulas for each scenario.

### a. **Present Value using the Discount Rate**
The formula for the present value using a discount rate is:

\[
PV = \frac{FV}{1 + \left(\frac{r \times t}{360}\right)}
\]

Where:
- \( PV \) = Present Value
- \( FV \) = Future Value = P115,000
- \( r \) = Discount rate = 15% or 0.15
- \( t \) = Time period in days = 200

Substituting the values:

\[
PV = \frac{115,000}{1 + \left(\frac{0.15 \times 200}{360}\right)}
\]

Let's calculate this:

\[
PV = \frac{115,000}{1 + \left(\frac{30}{360}\right)} = \frac{115,000}{1 + 0.08333} = \frac{115,000}{1.08333} \approx P106,137.95
\]

### b. **Present Value using Simple Interest**
The formula for present value using simple interest is:

\[
PV = \frac{FV}{1 + \left(\frac{r \times t}{360}\right)}
\]

Here, the formula is similar to the discount rate, but it applies to simple interest. The calculation will be the same:

\[
PV = \frac{115,000}{1 + \left(\frac{0.15 \times 200}{360}\right)} \approx P106,137.95
\]

However, this is unusual because discounting usually results in a smaller present value than simple interest. But since both use the same formula and time period, they produce the same result. If this seems off, it might be worth double-checking specific contexts or assumptions of the problem.

### Final Answers:
- **a. Discount Rate:** P106,137.95
- **b. Simple Interest:** P106,137.95
