# Long-Term Investments Exercises 41-48 are based on the following table, which lists interest rates on long-term investments (based on 10-year government bonds) in several countries in 2014.37 [HINT: See Example 2.] Country U.S. Japan Germany Australia Brazil Yield 2.5% 0.5% 1.0% 3.5% 4.2% If the interest on a long-term Australia investment is compounded continuously, how long will it take the value of an investment to double? (Give an answer correct to two decimal places.)

To determine

To calculate: The time required for an investment to be double its value in Australia if the interest is compounded in continuously.

Explanation

Given Information:

The returned amount is double of its investment amount.

The interest is compounded continuously.

The interest rate table is,

 Country U.S. Japan Germany Australia Brazil Yield 2.5% 0.5% 1.0% 3.5% 4.2%

Formula used:

The relation between growth constant and doubling time is,

tdk=ln2

Here, td is doubling time.

The relation between growth constant and rate of interest is,

k=r100

Here r is the percentage rate of interest.

Calculation:

The rate of interest in Australia is 3.5%.

Substitute r=3.5 in the formula k=r100,

k=3
