It's a good idea to have a regular savings plan. Let us assume the following scenario: Start with $142 and invest a further $102 each (end of the) month for 3 months (i.e. you make 3 more payments after the initial payment). The interest rate over this period of time is 5% per month. The interest rate changes immediately after your last payment. Then, being a bit cash strapped, at the end of the month you withdraw $185 for the next 2 months (i.e. you withdraw $185 two times). The interest during this period is 3% per month. The interest rate changes immediately after your last withdrawal. Having improved your finances, you continue with your savings plan and invest $140 each (end of the) month for 2 months (i.e. you make another 2 payments). The interest rate for this period is 2% a month. How much money do you have in total immediately after your last contribution? [Do not round intermediate results.
