# Using Table 11-1, calculate the compound amount and compound interest for the following investment.Principal Time Nominal Interest Compound CompoundPeriod (years) Rate (%) Compounded Amount Interest____________________________________________________________________________$400 2 6 monthly __________ __________ To determine To calculate: The compound amount and the compound interest for the investment with principal$400 is made for 2 years at 6% compounded monthly by using table.

Explanation

Given information:

An investment with principal $400 is made for 2 years at 6% compounded monthly. Formula used: Compounding period can be defined as the duration or length of time from one interest payment to the next. If an investment made for 4 years at 6% compounded annually (once per year) then it would have four compounding period which can be calculated by formula given below: Compounding periods=Term of investments(years)×m Here, m is the period per year. The interest rate per period can be calculated by dividing the annual, or nominal, rate by the number of periods per year, Interest rate per period=Nominal ratePeriod per year The compound amount (Future value) can be calculated by the formula given below: Compound amount=Table factor×Principal In table 11-1, the table factor is the intersection of the rate-per-period column and the number-of-periods row is the future value of$1 at compound interest.

The compound interest can be calculated by the formula given below:

Compound interest=Compound amountPrincipal

Calculation:

Consider the investment with principal \$400 is made for 2 years at 6% compounded monthly and solve as shown below:

Since, the variables- principal, time period (years), nominal rate and interest compounded are given; therefore, the compounding period can be calculated as below:
