Marketing math question

[hanlen]

Hey I really need help on how to solve this problem, thank you in advance:

A store sells an item it originally marked up 30% of the cost price, at a discount of 58% of the selling price. What percent of the cost is the resulting profit or loss on this sale?

Is this homework?
Please show where you're stuck.
Did you read this site's rules?

Ya it is.

I'm pretty lost on this one.

This is where I've got:

S = c + m
= c + .30c
= 1.30c

S made-up = 10

10 = 1.30c
c = 7.69


I don't know where to go from here..

Also, I haven't read the site rules yet.

Pick a generic amount, something that's nice and neat, so you can compare easily; say, $100.

If the cost was $100, then what was the original selling price?

The store then marks the item down 58%. What percent then remains, that the store is charging? How much of the original selling price is this amount?

How does this amount compare with the original cost of $100? What percent is this?
