Hi all, i'm after a bit of advice, problem is i'm not that great with word problems i am stuck on a couple and i am wodering if anyone has any tips for solving word problems and forming equations from them?? Here is one i'm a bit stuck on.

The cost of an anorak rose by £6. As a result a shop could buy 5 fewer anoraks for £600. If the cost of the anorak was £x before the rise, find expressions, in terms of x,for the number of anoraks which could be bought before and after the rise. Hence form an equation in x and show that it reduces to x^2+ 6x-720=0. solve this equation and state the original cost of the anorak.

can somebody tell me how i should go about doing these??

Thanks,

Chris.
