Write a function [change, flag] = makechange(cost, paid)that takes the cost of an item cost (a 1x1 double) and the amount paid by the buyer paid (a 1x1 double), and returns a n x 1 column array of doubles change containing the bills that the seller should give back to the buyer in decreasing bill size ( from $100-$1) and flag a 1x1 logical true or false saying whether the transaction was "completed". if paid is less than cost, flag is false and you should display a warning in the command window saying "that’s not enough money to buy the item." and change is assigned as an empty array. if cost and paid are equal the change is a 1 x 1 double of value zero and flag is true. if paid is greater than cost, flag is true and ch

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year.txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)
