Math Problem Statement

After 538 ​years, the balance obtained by investing ​$222 at a rate of 2​% with annual​ compounding, will be ​$    enter your response here.

Solution

To calculate the balance after 538 years with annual compounding, we can use the formula for compound interest:

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

Where:

  • AA is the final amount (balance).
  • P=222P = 222 is the principal (initial investment).
  • r=0.02r = 0.02 is the annual interest rate (2%).
  • n=1n = 1 is the number of times the interest is compounded per year (annually).
  • t=538t = 538 is the time in years.

Substituting the values:

A=222(1+0.021)1×538A = 222 \left(1 + \frac{0.02}{1}\right)^{1 \times 538}

A=222(1.02)538A = 222 \left(1.02\right)^{538}

Now, I will compute the value of AA.The balance after 538 years of investing $222 at a rate of 2% with annual compounding will be approximately $9,402,544.17.

Here are five related questions to expand on this topic:

  1. What is the difference between annual and continuous compounding?
  2. How would the balance change if the interest rate was higher, say 5%?
  3. What would be the effect of compounding more frequently, such as quarterly?
  4. How do you calculate the time required for an investment to double at a specific interest rate?
  5. What is the formula for calculating compound interest with monthly compounding?

Tip: Increasing the compounding frequency (e.g., quarterly or monthly) leads to a slightly higher final balance compared to annual compounding at the same interest rate.
