Can you just give me the equation to it?

we can see it from this way.

when the Costs = Revenuve, is the equilibrium point, or break-even point, where there are no losses but no gains either, all costs are covered by the incoming revenue.

if say they have make "x" more, on top of the 98200 they already have, to make a profit, that amount must surpass the costs, since recall that profits are just the surplus.

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.
