Alright, thanks! I'll check google some more for Properties of Equality and inverse operations.

Hello, I'm doing some physics work where I need to isolate the varibles but I've sadly forgotten how to do this. I've never used this in my work for a few years now so I'm stuck on the steps. If anyone can direct me to a site or let me know the steps for isolating that would be great. I'm...

The problem has been solved. I mis-understood the question when doing the TVM Solver. I was supposed to put 0 for FV, not what I got from my Excel answer, then use the solve for PMT.

[SOLVED] TVM Problem solving the end amount. Homework Statement 2. A spreadsheet software or TVM solver on a calculator can be used to determine the equal monthly payments that can be paid from an annuity for a set length of time. You can enter different payments until you find the one that...

Blah, I see now. I left it in decimal form not as a percent. Thanks for the help!

Homework Statement 1. What interest rate is required to turn $1000 into $1500 in 5 years if the interest is compounded: a) annually b) monthly (round your answer to the nearest tenth of a percent)Homework Equations I'm using the formula: (A/P)^1/n - 1 = i...

I see what the problem was, I wasn't using brackets on my calculator. If I do 2^1/5 I get the wrong answer because it does 2^1 which is 2 then divides by 5 to get 0.4 instead of 2^(1/5) being 1.14869... Thanks for the help on seeing my error.

I'm having some trouble understanding how to solve for i. This is the formula for compounding interest. I'm reading this example which shows how to solve for i if you double your money in 5 years. So it gives this example: (A/P)^1/n - 1 = i So it gives A for 2 and P for 1, n would be 5...
