You are correct on your variables and 3-3 is correct. On 3-4, when you plug all your values into the Correlation and Regression calculator, you should get formula Y=-41.430+.125x. Plug in 700 for X (Y=-41.430+.125(700)) and you should get 46.07.
For 3-5, simply take the r obtained from your calculations you just did and square it. So r=.941 and when we square this we would get .86 (or 86%). I hope that helps and I followed Dr. Guy's directions in the previous blog to get these answers, so im almost 100% sure they are right :-)

When I squared .941, I got .8855 so 88.6%. Will that be considered correct?
