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.
I'll fan and medal
can somone please help
I have no idea and im in 7th grade... srry
Lets see who's smart
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.
Ok, lets do it step by step
It's just tricky because there's a lot of solving to do.
but who is correct? I thought its dan
So do you know how to solve for a discounted price and how to add tax?
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
what do I do next
Next do 24.50-3.65. (lots of people forget this other step)
so both of them can buy it?
Sorry, I'm back.
Next, add 10% tax to that.
please hurry I have to go soon
So in the end how would I explain this?
how would I?
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?
You're not done with the solving, so don't jump ahead.
I really can't figure it out
I'm fasting today so I haven't eated
I feel retarted
and I need to get this stuff done
Don't worry about it. Just slow down and think about it. You're solving how you just did, but with different numbers.
I just don't understand this type of math
It just makes no sense
I think the problem is in explaining it
Don't worry, that comes next. It'll be easy. First, Find 85% of 24.50.
11 dollars and 50 cents?
I got 20.83.
So they can both buy it?
So 24.50-20.83 is?
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.
