Hey guys, I am back again. This time with only 3 questions and needing some help with them.

1. A calculator is sold at $30 with a loss of 6%. What is the cost price of the calculator to the person who sold it?

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

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

I am confused by what the first equation would look like to be honest.


and the 2nd one was $11

Sorry

What is 6% of $30? Use that answer to figure out the original price.

Ratio of owner's selling price to his buying price

15% of $318.75, then figure out marked price.

For the first one I got $1.80, so would the answer be $31.80?

And I apologize, its sells for $16 and the owner pays $11

Tell Mrs. Romefalls to become a member so we can deal with her directly. :D

Not a bit! How are you doing with the first one?

I can't figure out the formula for this one I got the answer 31.80 but 1.80 is 6% of 30 so I think I'm doing it completely wrong

original cost = unknown = x
selling price = $30
loss = 6% or $1.80

What is x?

Think! Do you add $1.80 to $30 to subtract $1.80?

Was the original price higher or lower than $30?

The only thing I come up with is $31.80 but that seems completely wrong

It's correct. Why does it seem wrong?

1.80 is 6% of 30, so I would think that 6% of a larger number would be more

Naw.
10% of $30 = $3.00
25% (1/4) of $30 = $7.50
50% of $30 = $15
100% of $30 = $30

6/100 x 30/1 = 18/10 = 1.8 = 1.80

I suppose I'm just over thinking it... I tend to make things appear more difficult than they actually are.

Yes, you're thinking too much.

How are you at cooking?

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?

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

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

Good girl!

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?

16/11= 1.45%?

No. How much profit in dollars?

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