![### Investment Analysis for Emission Reduction Equipment
**Scenario:**
Carlisle Company has been cited and must invest in equipment to reduce stack emissions or face EPA fines of $20,500 per year. An emission reduction filter will cost $75,000 and have an expected life of 5 years. Carlisle's Minimum Acceptable Rate of Return (MARR) is 10% per year.
**Problem:**
**Part A**
- *Question:* What is the future worth of this investment?
**Instructions:**
Carry all interim calculations to 5 decimal places and then round your final answer to the nearest dollar. The tolerance is ±10.
### Steps for Calculation:
1. **Initial Data:**
- Cost of the emission reduction filter = $75,000
- Life span of the filter = 5 years
- Fines avoided per year = $20,500
- Minimum Acceptable Rate of Return (MARR) = 10% per year
2. **Formula for Future Worth (F):**
The future worth of the savings can be calculated using the Future Worth formula for uniform series savings:
\[ F = P \times \left( (1 + i)^n - 1 \right) \div i \]
Where:
- \( F \) = Future worth
- \( P \) = Annual savings ($20,500)
- \( i \) = Interest rate (10% or 0.10)
- \( n \) = Number of years (5)
3. **Calculation:**
\[ F = 20,500 \times \left( (1 + 0.10)^5 - 1 \right) \div 0.10 \]
4. **Detailed Computation:**
- Calculate \( (1 + 0.10)^5 \)
- \( (1.10)^5 = 1.61051 \)
- Subtract 1 from the result:
- \( 1.61051 - 1 = 0.61051 \)
- Divide by the interest rate, \( i \):
- \( 0.61051 \div 0.10 = 6.1051 \)
- Multiply by the annual savings:
- \( 20,500 \times 6.1051 = 125,148.55 \)
