Catalina needs to take a taxi ride into town. the taxi fare is a $2 flat rate plus $0.75 each mile. catalina has only $12.50 to spend on the cab fare. what is the number of miles catalina can afford to travel by taxi is she spends exactly $12.50? a x 10 miles b x 12 miles c x 13 miles

The answer to your question is: 14 miles

I think you forgot letter D = 14 miles.

Step-by-step explanation:

Data

Flat rate = $2.00

each mile = $0.75

Catalina has = $12.5

Process

Cost of miles without flat rate = 12.5 - 2

                                                 = $10.5

Number of miles she can travel = 10.5 / 0.75

                                                    = 14 miles

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.

7 - 9 = -2
