To do this, the solution should have a menu with the following capabilities: Add Policy o This capability will allow a user to add a policy. The user should specify if the policy is for home, auto, or life. Once the type of policy has been selected, the user should be prompted for all required fields for the policy type. Remove Policy o This capability will allow a user to select any policy and remove it from the list. View policies o This capability will allow a user to see all the policies.

- I need help writing pseudocode for calculating class score average by putting in 5 test scores, and showing the average from all 5 inputs and the GPA score.Starting with 3 functions outside of a main module. The functions are getScore(), getGPAPoint(Integer score), and getAverage(). Function getscore is an input for a grade as a class percentage. Function getGPAPoint will calculate the score into a GPA point and return as a float (values of 90-100 as 4.0, 80-89 as 3.0, 70-79 as 2.0, 60-69 as 1.0, and anything below 60 as 0.) Function averageGPA will finally make a call to both previous functions when the user inputs numbers 5 times that then calculates the average (add up all the scores, divide by 5) and the average grade alongside displaying the average GPA. End result is a main module that makes a proper call to the averageGPA function and display its results. Need help with this!arrow_forwardPlease original work Why is integration between data collection and business analysis so important to success in an organization that uses business analytics?
