Khairul deposited $600 in a bank at the end of 2010 and another $400 in the same bank at the end of 2011. the bank offers simple interest at a rate of 3% per annum. find the total amount he has in his bank at the end of 2013.

Answer with Step-by-step explanation:

Khairul deposited $600 in a bank at the end of 2010 at the rate of 3 % per annum simple interest.

simple interest=

where P is the principal amount

r is the interest rate and t is the time

interest got till the end of 2011=

                                                 = $ 18

Khairul deposited $400 in the same bank at the end of 2011.

At the end of 2011 total amount in his bank= $(600+18+400)

                                                                       = $1018

Interest he got from end of 2011 till end of 2013=

                                                 = $ 61.08

Total amount in his bank at the end of 2013=$(1018+61.08)

                                                                        = $ 1079.08

Hence, total amount Khairul has in his bank at the end of 2013 is:

$ 1079.08

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
