You have decided you will no longer buy fodd from the cafetria.This will save you about $5 a day. You are going to do this the rest of the way through university.Assume you are saving during the summer as well. You have found an investment that will pay you 3.5%/a compounded monthly for 5.5 years. You are going to put the money away every month for the total time.
After your schooling yearsyou can save your money at 6.5%/a compounded semi-annually.You will not be making payments to this investment anymore.
After university, with your high paying job,you have decided to save $500 monthly at 6.5%/a compounded monthly for 35 years.Being the smart math students you are,you must determine the amount of money you will have in total.
We all know it is not fun being retired if you don't have money.So you want to take out as much money as you can every month for 25 years.You have found an investment that will pay n interst rate of 7.3%/a compounded monthly for the 25 years.What is the amount of money you can withdraw each month?
Some people are luckly and have large sums of money given to them in trust.One such person in our class is very luck.They have a very large sum of money in trust. They cannot touch it for 5 years.So for now they are getting 8%/a compounded semi annually.But in 35 years they get quarterly payments of $20500.If the interest rate they are getting is 7.5%/a compounded quarterly.How much money had been for them today?
