Clothing a company charges $6 to make a pattern for an order of t-shirts and $11 for each t-shirt it produces from the pattern. the expression $11n + $6 represents the cost of n t-shirts with the same pattern. find the total cost for 5 t-shirts with the same pattern.

$61

Step-by-step explanation:

It means that $6 is a fixed charge for pattern making on an order of shirts while the cost for the number of T-shirts produced is equivalent to the product of 11 and the number of shirts in dollars.

This explains the function $11n + $6 where n is the number of  T-shirts produced with the same pattern.

As such, the cost for 5 T-shirts will be

=11(5) + 6

=55 + 6

= $61

The total cost for 5 T-shirts with the same pattern is $61.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

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.
