Adjusted Gross Income Problem: Consider a software system that computes income tax based on adjusted gross income (AGI) and number of dependents according to the following rules: If AGI is between 25000 and 50000 and number of dependents less than 3, the tax due is 22% of AGI, otherwise, the tax rate is 20% If AGI is between 50001 and 100000 and number of dependents less than 3, the tax due is 27% of AGI, otherwise, the tax rate is 25% If AGI is between 100001 and 1 million and number of dependents less than 3, the tax due is 36% of AGI, otherwise, the tax rate is 33% This software doesnt calculate tax for people over 1 million and tax will not be deducted for families with AGI less than 25000

Suppose you need to test this application using equivalent partitioning a) Identify equivalent classes for income and number of dependents b) Develop test cases for weak normal equivalent partition testing c) Draw a graph that shows strong normal and strong robust test cases. How many test cases are needed if you are strong normal? How many test cases are needed if you are strong robust?
