Math Problem Statement

The following investment requires table factors for periods beyond the table. Using Table 11-1, create the new table factor, rounded to five places, and calculate the compound amount (in $, rounded to the nearest cent.) Principal Time Period (years) Nominal Rate (%) Interest Compounded New Table Factor Compound Amount $16,000 29 8 annually $

Solution

To solve this, we'll need to compute the compound amount for a principal of $16,000, with an interest rate of 8%, compounded annually over 29 years.

The formula for compound interest is:

A=P(1+rn)ntA = P \left(1 + \frac{r}{n}\right)^{nt}

Where:

  • AA is the compound amount.
  • PP is the principal amount ($16,000).
  • rr is the nominal annual interest rate (8% or 0.08).
  • nn is the number of times the interest is compounded per year (for annually, n=1n = 1).
  • tt is the time the money is invested or borrowed for, in years (29 years).

Step 1: Calculate the new table factor

The table factor corresponds to the value of (1+rn)nt\left(1 + \frac{r}{n}\right)^{nt}, which in this case simplifies to:

(1+0.081)1×29=(1.08)29\left(1 + \frac{0.08}{1}\right)^{1 \times 29} = (1.08)^{29}

Let's calculate this value.

The new table factor for this investment is approximately 9.31727 (rounded to five decimal places).

Step 2: Calculate the compound amount

Now, we use the formula for compound interest:

A=P×Table FactorA = P \times \text{Table Factor}

Substituting the values:

A=16,000×9.31727A = 16,000 \times 9.31727

Let's compute the compound amount.The compound amount for this investment is approximately $149,076.40, rounded to the nearest cent.

Related Questions:

  1. How would the result change if the interest were compounded semi-annually instead of annually?
  2. What would happen if the interest rate increased to 9%?
  3. How is the table factor calculated for different compounding periods, such as monthly or quarterly?
  4. What is the total interest earned over the 29 years in this scenario?
  5. How would a shorter investment period (e.g., 20 years) affect the compound amount?

Tip: Longer time periods exponentially increase compound growth, especially with higher interest rates, due to the power of compounding.
