Mrs. wheeler is looking to make a deposit of $2500 dollars into the savings account that earns simple interest at a rate of 2.02% per year. how many years will it take for her account to reach $3000 if she does not deposit or withdraw any money.

9.9 years

A = P(1 + rt) . . . . account balance after time t at rate r starting with principal P

... 3000 = 2500(1 + 0.0202t) . . . . filling in the given numbers

... 1.2 = 1 + 0.0202t . . . . divide by 2500

... 0.2 = 0.0202t . . . . . . subtract 1

... 0.2/0.0202 = t ≈ 9.901

It will take about 9.9 years for the account balance to reach $3000.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
