I need a person who knows how to write bash shell script files using virtual box and ubuntu

Write a Linux Bash shell script to compute the bonus for salespersons who are working at Mercedes Benz dealership who sell the following models: A class - £24,095 - £38,095 (average £31,095) B Class - £28,045 - £38,280 (average £33,162) C Class - £34,670 -£50,405 (average £42,537) E Class - £39,680 - £69,015 (average £54,437) AMG C65 - £78,103 - £81,217 (average £79,660) Each salesperson earns a basic salary of £2,000 per month. However: • If he or she achieves £200,000 worth of sales they will earn a bonus of £10,000 per month. • If he or she sells more than £300,000 worth of sales they will earn a bonus of £15,000 per month. • If he or she sells more than £400,000 worth of sales they will earn a bonus of £20,000 per month. • If he or she sells more than £500,000 worth of sales they will earn a bonus of £25,000 per month. • If he or she sells more than £650,000 worth of sales they will earn a bonus of £30,000 per month. Design a program which calculates, each salespersons salary per month. Calculate the tax each salesperson pays and hence calculate their total salary after tax. Inputs • Enter Month • Enter Salespersons name • Models he/she sold • Save the data o File name o File path Outputs • How to display results o Name order o Salary o Name with associated net salary The program should work for between 3 and 20 salespersons. Sorting You should employ a bubblesort (no marks will be awarded for the use of the bash sort command) to display a list of the SalesPersons. All inputs should be checked for valid data. Tax Rates Personal allowance- £12,500 – this is the amount you can earn before you start paying tax. Basic Rate - £12,501 to £50,00 is taxed at 20% Higher Rate- £50,001 to £150,000 is taxed at 40% Save this practical as it will be handed in as part of a portfolio on 19th July 2020. Remember to use regular expressions for error checking. i.e when you prompt the user to enter a value you should test to see if it a number/s or character/s are in the correct format.
