Figure it out.

I'll point out that if you bothered to understand the simple math behind what's going on, you wouldn't have to worry about whether you have the right answer or not. You'd be able to see whether it's correct or not on your own.

o my gosh so i spent hrs asking a question to be told to figure it out myself this website sucks, how do i delete my account

My point is that whether anyone tells you if your answer is right or wrong does absolutely nothing to help with your understanding. You're not going to have someone to ask during a test whether you did a problem right or not.

We've all tried to help you understand how to analyze the problem, but you've plainly stated you're not interested in learning that. If you don't want to learn it — which is a perfectly fine choice to make — we can't do anything about that. By the same token, none of us here is really interested in simply checking that you know how to use your calculator.

If you think you've done everything right, just go with the answer you got.
