Hi, Guest!
Please do not take offense, but I suspect that you are just posting all of your homework on the forum without trying!
1. This forum actually has a calculator that can be accessed by clicking the "Home" tab at the top of the page.
2. The forum is meant to help you with your homework, not do it for you.
For us to help you, it would aid us greatly if you could show us your work before posting...
Thanks!
