If you bought something for $100, and one week later sold it for $110,
what's your return on investment? Hopefully, you were able to answer
instantly that it's 10%. If not, maybe finance is not for you.

It's the same with returns on a stock price. The return on investment is
always:
=(EndingValue - BeginningValue) / BeginningValue

Hopefully you can take it from here. But if you need more help, post back.

Regards,
Fred.
