B. $250
C. $225
D. $255

Answer 2

ok i think this might b C or d but im not sure u have to tag someone else

Answer 3

Name the regular price.

Answer 4

It does not give the regular price.

Answer 5

Youre supposed to find it

Answer 6

That's why I told you to NAME it. Call it something so we can talk about it.

Answer 7

Seriously, call it "Steve", if you like. Just give it a name.

Answer 8

Okay, so this is a percent problem. The reduced price is $216.75 as we know. Are you asking me to choose on of the answer choices as an answer then we talk about it? If you are then I'm going to pick $250.00

Answer 9

#1 thing to do. If you don't know it's value, give it a name. Call it something. Once we have a name, we can write equations and create meaningful expressions.

Answer 10

Okay I think we will go with "Drew".

Answer 11

Fine. Drew = Original Purchase Price.

What is the discount? The discount percentage is 15%. Write an expression that represents the discount.

Answer 12

I'm not sure how to do that. D= 216.75

Answer 13

How about Drew * 15% = 0.15 * Drew

This is the Discount. Do you believe?

Answer 14

Yes. Okay 15% = 0.15 * Drew.

Answer 15

Okay, now we need an expression for the final purchase price.

Drew is the Original Purchase Price
0.15 * Drew is the Discount

Write an expression that represents the Sale Price.

Answer 16

D = $216.75 I hope this will suffice.

Answer 17

That's no good. That IS the final sale price. We need an expression containing the Original Price that REPRESENTS the final sale price.

Answer 18

I have no idea how to do that. All I could tell you about what your asking me is that it has Drew in it somewhere.

Answer 19

Yes you do. You do it all the time at the store.

If the price is $100 and the discount is $10, the sale price is $100 - $10 = $90. Just do that with Drew.

Answer 20

Okay. I'm going to try it. $Drew - 15% = $216.75

Answer 21

Drew - 0.15*Drew = $216.75

That's it!!! Good work.

How do we solve?

Answer 22

gtg

Drew - 0.15*Drew = $216.75

Distributive Property

Drew*(1 - 0.15) = $216.75

Resolve Parentheses

Drew*(0.85) = $216.75

Divide by 0.85

Drew*(0.85)/0.85 = $216.75/0.85
Drew*(1) = $216.75/0.85
Drew = $216.75/0.85 = $255.00 and we are done.

Once we get the name, we are off and running. Without the name, it is quite laborious.

I do recommend picking simpler names. I noticed you kept using "D". That is much simpler than "Drew". It doesn't matter much, though. Just pick names you can remember and write a good definition.

Answer 23

Well thanks.
