An internet charges a flat rate of $6.50 for shipping. If x represents the cost of items purchased and y represents the total cost of shipping. What equation represents the relationship between x and y?

Question:

An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?

y = 6.5 + x represents the relationship between x and y

Solution:

Given that,

An internet charges a flat rate of $6.50 for shipping

Let "x" be the cost of items purchased

Let "y" be the total cost with shipping

Therefore,

Total cost with shipping = flat rate of 6.50 + cost of items purchased

Thus, we get,

y = 6.50 + x

y = 6.5 + x

Thus the above equation represents the relationship between x and y

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.
