Ahh makes much more sense when Reiny did it. I remember learning this in algebra. I have a tendency to give everything its own variable, which makes the problem impossible to solve i guess.

algebra
x + y = 1,100 a + b = 49 (x+5%) + (y+2%) = 1,149 That's all I could take from the question. Now how you solve and get the answer is beyond me.

Proportions
It just depends on how the problem is actually written. Is 3y-8 all over 12 or is 8 just over 12? Because I solved 3y - (8/12) = (y/5), not [(3y-8)/12]= (y/5)...its just all in how you type your question.

y=5/21

Well if I had not read online that Emily Dickinson wrote a lot of poems about death, then I probably wouldn't have a clue to what it implies. However, I'll say it implies that "the storm" or the bad parts of her life is "o'er" or over or finished.
