Another brain teaser

[LVRebel]

Bill bought a phone at a store that gave a 20% discount off of it's original price. The total amount that he paid to the cashier was 'x' dollars, which includes an 8% sales tax on the discounted price. Which of the following represents the original price of the phone in terms of 'x'?

A) 0.88x
B) x/0.88
C) (0.8)(1.08)x
D) x/(0.8)(1.08)

Good luck!

Edit to add, no random guesses. You must explain why you chose what you did.

Computer price is irrelevant if the discount was on a phone.

Computer price is irrelevant if the discount was on a phone.

LOL, I messed up my own post. Fixed now. Thanks for pointing it out

probably wrong but..I will go D

x= original price (0.8 discount)(1.08 tax)
original price = x/(0.8)(1.08)

The correct answer is D.

 

[Edgehollow]

D. They figure sales tax on the sale price. Should have been written (x/.08)(1.08) though.

 

[Chuck 2020]

Correct answer is C.

 

[LVRebel]

probably wrong but..I will go D

x= original price (0.8 discount)(1.08 tax)
original price = x/(0.8)(1.08)

Nailed it. Good job. I first read it and chose C because I didn't read the question right and see that they wanted to know the 'original' price, and not the price that Bill paid.

Give me the D
