These two problems are really confusing me, can someone explain them to me?
1) The Eiffel Tower is 497 ft. taller than the Washington Monument. If each of the monuments were 58 ft shorter, the eiffel tower would be twice as tall as the washington monument. How tall is each?
and...
2) Nine cartons of juice cost the same as 5 fruit cups. Also, one fruit cup costs 50 cents more than one bowl of soup, while one bowl of soup costs 50 cents more than one carton of juice. What would be the cost of each item: a carton of juice, a fruit cup, and a bowl of soup?

Thank you VERY much!

I realize that a(b+c) = ab + ac. It works. But why? I can create a geometric proof... even an algebraic proof... so see how it works for integers. But how can it be verified that it works for all rational and irrational and even transcendental numbers?

I've been trying to figure it out for hours. I went to tutoring and they couldn't help, I tried it in my calculator and it even broke, I called Chuck Norris and he roundhouse kicked me, I tried with my fingers and toes and all the nails broke, I called Jesica Simpson and she told me it was a kind of fish that usually comes in a can, I asked my math teacher and she doesn't get it neither; we are working together to solve it by next week!

What should I do?

Thanks a lot for your help
