Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences.

Lets see who's smart

- horsegirl27

Here's what you have to do. You have to solve it their ways, and choose who is correct. Next you have to answer the quest about them having enough money.

- anonymous

Ok, lets do it step by step

- horsegirl27

It's just tricky because there's a lot of solving to do.

- anonymous

yeah

- anonymous

but who is correct?
I thought its dan

- horsegirl27

So do you know how to solve for a discounted price and how to add tax?

- anonymous

yes

- anonymous

multiply?

- horsegirl27

Ok, so Tess is correct, but you still have to solve both their work for you to answer the other part. So start by finding 15% OF 24.50

- anonymous

Ok

- anonymous

3.65?

- anonymous

@horsegirl27

- anonymous

what do I do next

- horsegirl27

Next do 24.50-3.65. (lots of people forget this other step)

- anonymous

20.85

- anonymous

so both of them can buy it?

- anonymous

???

- anonymous

Horse?

- anonymous

@horsegirl27

- horsegirl27

Sorry, I'm back.

- anonymous

@LynFran

- horsegirl27

Next, add 10% tax to that.

- anonymous

10%

- anonymous

2.8 cents?

- anonymous

please hurry I have to go soon

- horsegirl27

It's 2.085.

- anonymous

oh

- anonymous

So in the end how would I explain this?

- horsegirl27

$2.10

- anonymous

@horsegirl27

- anonymous

how would I?

- anonymous

.

- horsegirl27

I'm still here. First, you have to add $2.10 to 20.85. That will be the price for Tess. Now I want you to try solving for Dan yourself. Use the same steps, different numbers. What do you get in the end?

- horsegirl27

You're not done with the solving, so don't jump ahead.

- anonymous

I really can't figure it out

- anonymous

I'm fasting today so I haven't eated

- anonymous

I feel retarted

- anonymous

and I need to get this stuff done

- horsegirl27

Don't worry about it. Just slow down and think about it. You're solving how you just did, but with different numbers.

- anonymous

I just don't understand this type of math

- anonymous

It just makes no sense

- anonymous

I think the problem is in explaining it

- horsegirl27

Don't worry, that comes next. It'll be easy. First, Find 85% of 24.50.

- anonymous

11 dollars and 50 cents?

- horsegirl27

I got 20.83.

- anonymous

So they can both buy it?

- horsegirl27

So 24.50-20.83 is?

- anonymous

3.67

- horsegirl27

Now do your next step it tells you do to. THEN you can answer the questions. I can tell you right off that Tess is right. Now by solving you'll see if they both can afford it. Your explanation will just be answering the 2 questions and then just use the work you showed here. Now I must go, sorry.
