What does 30% mean in terms of money

Explanation below.

Step-by-step explanation:

Let's say for example you have 100 dollar or euros, or whatever you work with in your country. 30% of 100 equals 30.

If they ask you for example 30% of 250 dollar/euro, it is 250/100 * 30, which equals 75.

If they say there are sales that go up to 30%, all you do is as follows;

1) You calculate how much money 30% is. [Look above]

2) You distract the 30% FROM the original price.

Example; A shirt costs 300 dollar/euro, but there's a sale of 30% on it.

30% of 300 = 100

300-100 = 200

The shirt costs 200 dollar/euro.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

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.
