Certainly, let's break down the calculations for these debt scenarios.
**1. Marry's Debt**
**1.1.1. Present Value of the Debt Now**
* **Given:**
* Future Value (FV) = 500
* Interest Rate (r) = 15% per year = 0.15
* Time (t) = 8 months = 8/12 years = 2/3 years
* **Simple Interest:**
* Interest = Principal * Rate * Time
* Interest = 500 * 0.15 * (2/3) = 50
* **Present Value (PV):**
* PV = FV - Interest
* PV = 500 - 50
* PV = 450
**Therefore, the single payment Marry needs to make now is 450.**
**1.1.2. Present Value of the Debt Six Months from Now**
* **Time Remaining:** 8 months - 6 months = 2 months = 2/12 years = 1/6 years
* **Future Value (FV) at 6 months from now:** 500 (remains the same)
* **Simple Interest:**
* Interest = 500 * 0.15 * (1/6) = 12.50
* **Present Value (PV) at 6 months from now:**
* PV = FV - Interest
* PV = 500 - 12.50
* PV = 487.50
**Therefore, the single payment Marry needs to make six months from now is 487.50.**
**1.1.3. Present Value of the Debt in One Year**
* **Time Remaining:** 8 months - 12 months = -4 months (This means the due date has already passed)
* **Since the due date has already passed, Marry would need to pay the full amount plus interest accrued for the past 4 months.**
* **Interest Accrued:** 500 * 0.15 * (4/12) = 25
* **Total Payment:** 500 + 25 = 525
**Therefore, if the payment is due in one year, Marry needs to pay 525.**
**2. Promissory Note**
**2.1.1. Maturity Value of the Note**
* **Given:**
* Principal (P) = 15000
* Discount Rate (r) = 16% per year = 0.16
* Time (t) = 6 months (April 1 to October 1) = 6/12 years = 0.5 years
* **Discount:**
* Discount = P * r * t
* Discount = 15000 * 0.16 * 0.5
* Discount = 1200
* **Maturity Value (MV):**
* MV = Principal - Discount
* MV = 15000 - 1200
* MV = 13800
**Therefore, the maturity value of the note is 13800.**
**2.1.2. Present Value on the Date of Sale (July 1, 2021)**
* **Time Remaining to Maturity:** 3 months (July 1 to October 1) = 3/12 years = 0.25 years
* **Discount from Sale Date:**
* Discount = Maturity Value * r * t
* Discount = 13800 * 0.16 * 0.25
* Discount = 552
* **Present Value on the Date of Sale:**
* Present Value = Maturity Value - Discount
* Present Value = 13800 - 552
* Present Value = 13248
**Therefore, the present value of the note on the date of sale (July 1, 2021) is 13248.**
