# Is this right? watch

1. I know this is simple, but it annoyed me, and I want to know if I've done it right or not, because the book doesn't tell you how you should have answered it.

Question:

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

So I did this:

Before rise:
After: or

=

Simplified to get

Then divided it all by 5 to get what was asked. So the original price was
£24.

Is that how I was supposed to do it?
2. Looks right.
3. Or -30 pounds.
4. (Original post by Simplicity)
Or -30 pounds.
Wouldn't that be good?
They give me £30 if I want an anorak.

Would give me a reason to wear one xD
