What sum will yield $1200 as simple interest after 3 years at 8% per annum?

The answer is $5000. With simple compounding you just look for the amount x=1200/(0.08*3), because you take three times 8% from the base amount x. Now you can calculate 8% from $5000 which is 400, so for three years it's 1200.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
