Try to think it this way:
Real world => word problem in math class => math problem => math equation (now use algebra) => solution => Real world
Most people do that so fast they don't even notice.
The Rules of Algebra are math's way of telling you to be reasonable, for example:
The Distributive property: (a + b) x c = (a x c) + (b x c);
In other words: Bob has two pockets, he has a ten dollar bill and a one dollar bill in each. All in all he has ($10 + $1) x 2 = $22. If he puts the two one dollar bills in his right pocket and the two ten dollar bills in his left pocket he still has $22.
The rules of algebra do not change when you apply them in the real world, they are all valid.

Shot answer: All of them
Long answer: Go do a Phd in Mathematics
once you understand the rules it is easy but if not it get real difficult
Algebra helps you solve real-world problems that you will face when you are on your own.
Some sequences are defined by rules and algebra is a mathematical way of describing rules.

Every science uses algebra, every social science uses algebra and all business uses algebra. And that is only a few of the places algebra is used in the real world. Science. Can not do chemistry stoichiometry without algebra. Social science. Stats are big in social science and their manipulation is algebraic. Business. Try figuring out future interest rates without algebraic formulas.

By definition, none. For if it did have real life applications it would not be called abstract! +++ You could consider it as establishing the rules by which the algebra needed to perform real-life tasks works. For a simple example, if C = AB then you could say, "Fine, suppose we call A and B the sides of rectangle than C is its area, OR if we call A and B speed and time respectively then C is the distance travelled. In both cases the algebraic rules are the same: multiply two values and you obtain their product; but many practical applications are in fact simple products so there we have the underlying pure algebra for solving them. And from that we can use pure algebra rules to determine A or B from the others.
The same way you do for simple algebra. The complication on each side don't change the rules; you are still doing algebra.
no one!
in cookingAlgebra can be used for many things in the real world. There are many practical examples where equations can be written using the known data and than algebra can be used to solve them.
algebra is the answer to your question!
