Question

Chapter 4, Problem 21P

To determine

Interest Rate.

Expert Solution & Answer

Answer to Problem 21P

7.242% is the interest rate.

Explanation of Solution

Given information:

Using linear interpolation, values to be found for (F/A,11%,15) and (F/P,16%,25).

With this problem, start with the interpolation exercise. Here, the goal is to try to find the interest rate from information that is available to us. Since the interest rate is not known for 6.25% but for 6.00% and 7.00%, split the difference to try to get the amount. Located below are the two values for the available information:

(P/A,6.00%,10%)=7.360

AND

(P/A,7.00%,10)=7.024

As of the result, apply the interpolation formula this can be seen as below:

(P/A,6 1 4 %,10) = 1 2 (Annuity Factor of the lower limit)− (Annuity Factor of the Upper Limit

+ (Annuity Factor of the upper Limit)

= 1 2 (P/A,6%,10)−(P/A,7%,10) +(P/A,7%,10)

= 1 2 (7.360−7.024)+7.024

= 1 2 (0336)+7.024

= 0.168+7.024

= 7.192

Thus, by using the interest tables and linear interpolation, the end result for this part of the problem is a factor of 7.192.

Now, apply the TVM calculator that is needed for the second part of the problem. There are a number of ways that one can do this first option is a financial calculator a second option is the use of an online calculator.

To expedite the comparison between the two, the end result of our use of either method is the following information:

(P/A,6.25%,10)=7.274

Therefore, if a TVM calculator is used, the result of the exact calculation is a factor of 7.274

However, there are two different numbers here. The estimate using linear interpolation is a little bit higher than the exact equation.

Conclusion:

The truth of the matter is that when one is doing an estimate between two time periods and applying the interpolation formula, it is not exact and will have some error. Thus, using the TVM calculator will be the most accurate factor possible.

Respond to this post. Hello Professor, A rise in consumption in the economy would cause an increase in aggregate demand. Therefore, when consumers spend money on everyday goods and services, it not only helps to stimulate economic growth, but it could also present potential issues like unsustainable debt levels or inflation. I believe that it would be beneficial to consider such factors and adopt a purchasing strategy to help navigate the challenges posed by inflation or unsustainable debt levels. First, do you think our business will be affected because inflation is rising? How? Yes, I do believe that the business will be affected because of inflationary pressures. Inflation rising will affect the cost of goods, services, and labor, which could lead to higher operating expenses. The potential reduction of profit margin because of inflation could lead to a smaller percentage of revenue being retained as profit. Therefore, inflation rising will force us to raise prices for…

Answer to Problem 21P

7.242% is the interest rate.

Explanation of Solution

Given information:

Using linear interpolation, values to be found for (F/A,11%,15) and (F/P,16%,25).

With this problem, start with the interpolation exercise. Here, the goal is to try to find the interest rate from information that is available to us.
