Susan purchased a government bond which has maturity value of $1,000 after 18 years at 12
3/4% simple interest. How much should she pay for this bond?

Please help with step-by-step

435.729847495 = 435.73

Step-by-step explanation:

I = prt/100

p=?

r=12³/₄= 51/4

t= 18

i = $1000

1000= (18x51/4xP)/100

1000X100 = (9XPX51/2) = 100000

459P = 2 X 100000= 200000

P = 200,000/459 = 435.729847495

she should pay $303.49 for this bond

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the government bond.

P represents the principal or amount paid for the government bond.

R represents interest rate

T represents the duration of the government bond.

From the information given

P = 1000 - P

R = 12.75%

T = 18 years

Therefore,

1000 - P = (P × 12.75 × 18)/100

1000 - P = 229.5P/100

1000 - P = 2.295P

1000 = 2.295P + P = 3.295P

P = 1000/3.295

P = 303.49

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.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
