The only thing tricky here is you trying to get other people to do your homework for you.

To calculate percentage change, take the DIFFERENCE (the final value minus the starting value) and divide that by the starting value, then multiply this result by 100 (just move the decimal two places to the right).
To calculate what percentage something is of the whole, divide the part by the whole and multiply the result by 100.
The "multiply the result by 100" bit is because "percent" is a contraction of the latin phrase "Per Centum" which literally means "for every one hundred." You have claculated the change or amount for every one, so you multiply this by a hundred to get the change or amount for every one hundred.

Yeah I can. You are trying to get 11 answers for the price of one. That means 10 out of 11 for free, which is a 91% rebate.

Why do you want us to do all of your homework? You will never learn that way....I think you need to do it yourself.
