I'm assuming after, so you would do y minus the 18% off, plus 8% of the discounted price.

- StudyGurl14

To calculate the discounted price, you would do the original price, y, minus 18% of y.

can you explain how you get the answer in steps please :)
@StudyGurl14 @Michele_Laino @welshfella

Okay, so you have the item at the original price, y. Correct?
Then it's on sale for 18% off. So you do 18% times y to get how much money off of the price.
Then to find the actual discounted price, you do the original price minus the discount, which is \(y-(18\%)y\)

but can you write it like this so i understand it better... please thx :)
1...

Then, you have to add sales tax, which is 8%. So, you take that expression up there, multiply it by 8% to find the amount of the tax, which you then add to the expression to find the total amount paid.

1. Find discount (amount off): (18%)y
2. Simplify: 0.18y
You with me so far?

- anonymous

yea.. continue :) @StudyGurl14 but can you also like answer it as your going :)

- StudyGurl14

3. Next, find the discounted price.
Original Price - discount off = y - 0.18y
Which equals what?

- anonymous

but can you add everything in.. like give me the complete answers in the steps please :)

- anonymous

can we start from step 1 again please @StudyGurl14 ill do it with you

- StudyGurl14

I don't understand what you want...?
Step 1: Find discount (amount off of original price)

- anonymous

what i mean is to like not add the parentheses for example...
dont do this: (amount off of original price)
actually put the answer .. you get me?

- StudyGurl14

I did. I put this --> (18%)y

- StudyGurl14

that's the answer to step 1

- anonymous

exactly so whats step 1 completely

- StudyGurl14

Um...? Like this?
1: (18%)y

- anonymous

so this is step 1:
Find discount ( 18%)y

- StudyGurl14

Okay....the parenthesis is just to further clarify. Sorry if it confused you.
1: Find discount - (18%)y
2: Simplify: 0.18y
3. Find discounted price - y - 0.18y
4: Simplify: 0.82y
OK?

- StudyGurl14

5: Find sales tax: (8%)(0.82)y
6. Simplify: (0.08)(0.82)y

- StudyGurl14

7: Simplify: 0.0656y
8. Find total paid: 0.82y + 0.0656y
9: Simplify: 0.8856y

- anonymous
