Well, pretend you are here cooking right now.

Let's do #3 while we're on a roll (and it's a similar kind of problem).

3. A store offers a discount of 15% on all it's sold. A shopper pays $318.75 for purchases made. What is the marked price of the goods purchased?

x = marked (original) price
15% = discount or sale amount that was taken off x
$318.75 = sale price

Now what?

Discount of 47.81? Which would bring the total to $366.56?

Um, how did you get that figure of $47.81?

$318.75 x .15 = 47.8125... I just rounded I suppose I'm wrong on this one.

15% of x = $318.75

15/100 of x = $318.75

100/15 times 15/100 of x = $318.74 times 100/15

this cancels out so --
x = $318.75 times 100/15
x = ?

Completely lost

Stop throwing around all those x's!

I come up with 2125 and that doesn't sound anywhere close

15% of x (x = total price) = $318.75 (discount price)

15/100 (another way of saying 15%) of x = $318.75

100/15 times 15/100 of x = $318.74 times 100/15

I did the above to cancel out to 1/1.

What you put on one side of an equation, you have to also put on the other side.

x = $318.75 times 100/15

x = ?

Did you keep and then position your decimal point?

That's correct, but where oh where is the decimal point in that answer?

I didn't, 21.25 sounds better

You're not finished. That's the discount. What is the original price?

That would be $340

Save your thanks. Let's press on into the wilderness.

2. A shop sells compact disks for $16 per piece. If each disk costs $11 to the shop owner, how much profit percent does the shop owner earn?

(I'll have to give Mr. Romefalls a lesson in punctuation some day... )

What should we do with #2?

How much profit is there in dollars?

16/11= 1.45%?

No. How much profit in dollars?

The question actually asked for the profit percent, did he forget to put that?
