**Problem 3-4: Calculating Future Value with Interest Rate**

**Question:**
At an interest rate of 10% per year, $100,000 today is equivalent to how much a year from now?

**Contributors:**
This problem was contributed by Hamed Kashani, Saeid Sadri, and Baabak Ashuri from the Georgia Institute of Technology.

This question is an example of calculating the future value of an investment or amount of money given a specific annual interest rate. The problem focuses on understanding how much a principal amount will grow in one year given the interest rate.

### Concept Explanation

To solve this, you can use the future value formula for simple interest:

\[ \text{Future Value} = \text{Present Value} \times (1 + \text{Interest Rate}) \]

Given:
- Present Value = $100,000
- Interest Rate = 10% per year or 0.10 in decimal form

Plugging the values into the formula, you get:

\[ \text{Future Value} = 100,000 \times (1 + 0.10) \]
\[ \text{Future Value} = 100,000 \times 1.10 \]
\[ \text{Future Value} = 110,000 \]

So, at an interest rate of 10% per year, $100,000 today will be equivalent to $110,000 a year from now.

### Application

Understanding this calculation is essential in financial planning, investment analysis, and comprehending how interest rates affect the growth of an investment over time. By mastering these concepts, students can make informed financial decisions and better anticipate the future value of their investments or savings.
