Question
![**How Much Money Will Be Accumulated in 20 Years?**
Consider a deposit of $1500 made every 6 months with an interest rate of 2.75% per month. This problem requires the use of interpolation to calculate the interest rates accurately.
### Graph Description
**Figure 2-10: Linear Interpolation in Factor Value Tables**
The graph depicts linear interpolation in factor value tables. Here’s a breakdown of the elements:
- **Factor Value Axis**: Represents the factor values used for calculations.
- **Horizontal Line (Linear Assumption)**: Connects known and unknown values, highlighting the assumption of linearity for interpolation.
- **Vertical and Horizontal Segments**: Indicate distances or differences between values on the axes.
### Formulas
1. **Main Interpolation Formula**
\[
f = f_1 + \left(\frac{x - x_1}{x_2 - x_1}\right)(f_2 - f_1)
\]
Where:
- \( f \) is the interpolated factor.
- \( f_1 \) and \( f_2 \) are known factor values.
- \( x \) is the unknown value we are solving for.
- \( x_1 \) and \( x_2 \) are known values on the axis.
2. **Alternative Formula**
\[
f = f_1 + \frac{a}{b} = f_1 + c = f_1 + d
\]
Here, \( a \), \( b \), \( c \), and \( d \) are incremental values used to achieve interpolation, representing adjustments made during the process.
This methodology allows for precise calculations of accumulated interest over time, using step-by-step interpolation within the context of factor value tables.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F844ad2f3-b020-401f-819e-f7e91676f808%2F88dddfbf-4b1b-4b97-9593-214622f38b52%2Fppd15d_processed.jpeg&w=3840&q=75)
