Answer 1

Answer 2

Is the sales tax before or after the discount?

Answer 3

after

Answer 4

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

Answer 5

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

Answer 6

can you explain how you get the answer in steps please :)

Answer 7

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 \(y-(18\%)y\)

Answer 8

but can you write it like this so i understand it better... please thx :)
1...
2...

Answer 9

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.

Answer 10

@StudyGurl14

Answer 11

1. Find discount (amount off): (18%)y
2. Simplify: 0.18y

You with me so far?

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

Answer 16

I don't understand what you want...?

Step 1: Find discount (amount off of original price)

Answer 17

Answer 19

Answer 20

Answer 21

1: (18%)y

Answer 22

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

Answer 23

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?

Answer 24

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

Answer 25

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