Please written by computer source   Unit 4 - Lab – Individual Retirement Account Calculation Assignment An Individual Retirement Account (IRA) is a special bank / brokerage account that a person can use to save money for retirement. An individual can put up to $5,500 per year tax free and the money grows tax free until the person is ready to retire. The tax rules related to IRA’s are complex, but for this assignment, we’ll assume that the person puts in the same amount of money every year (up to $5,500) and the money grows at a constant interest rate. Write a Flowgorithm program that asks the user to input an annual IRA contribution (in dollars), and interest rate (percent), and a time period (years). Calculate the value of the IRA every year for the duration of the time period provided by the user. Be sure and provide user friendly prompts. Include a comment at the beginning of the program with your name, date, and a short description of the program.

GradesGraphDemo (one method)- Main method only GradesGraph- Include at least 4 methods (No credits without at least 4 methods!!!) Create a class that represents the grade distribution for a given course. In this class you should write methods to perform the following tasks: Read the number of each of the letter grades A, B, C D and F Set the number of letter grades A, B, C, D and F Return the total number of grades Return the percentage of each letter grade as a whole number between 0 and 100 inclusive Draw a bar graph of the grade distributionThe graph should have five bars, one per grade. Each bar can be a horizontal row of asterisks, such that the number of asterisks in a row is proportionate to the percentage of grades in each category. For example, let on asterisk represent 2%, so 50 asterisks correspond to 100%. Mark the horizontal axis at 10% increments from 0 to 100% and label each line with a letter…
