Used to work as a prep cook in a restaurant but haven't done much of it lately.

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?

[Romefalls19]

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

[Wondergirl]

discount of 47.81? which would bring the total to $366.56?

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

[Romefalls19]

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

[Wondergirl]

$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 = ?

[Romefalls19]

Completely lost

[Wondergirl]

Solve for x.

Stop throwing around all those x's!

[Romefalls19]

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

[Wondergirl]

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 = ?

[Wondergirl]

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

Did you keep and then position your decimal point?

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

[Romefalls19]

I didn't, 21.25 sounds better

[Wondergirl]

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

[Romefalls19]

That would be $340

[Wondergirl]

That would be $340

Good girl!

[Romefalls19]

Thank you so much!

[Wondergirl]

Thank you so much!

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?

[Romefalls19]

16/11= 1.45%?

[Wondergirl]

16/11= 1.45%?

No. How much profit in dollars?

[Romefalls19]

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