Stick price = 45,500.
Discount of 20% (or 1/5) = 9,100.
Discounted Price = 45,500 - 9,100 = 36,400.
5% of 36,400. Well 10% of 36,400 = 3640. So 5% would be half of that, or 1820. Answer is D

Tax = 5% of Purchase price

=> Tax = 5% of [80% of Sticker price]; After the 20% discount, the purchase price = (100 - 20)% of Sticker price

=> Tax = 5% * 80% * Sticker price

=> Tax = [5/100]*[80/100]*45500

=> Tax = 1/20 * 4/5 * 45500 = $1820.

OA: D

Hi alanforde800Maximus,

The answer choices to this question are 'spread out' enough that you can do some estimation (without having to do every exact calculation).

The starting sticker price on a car is $45,500, which I'll 'round down' to $45,000.
The 20% discount off of THAT price would be: $45,000 - (.2)($45,000) = $45,000 - $9,000 = $36,000
The 5% tax on the $36,000 = (.05)($36,000) = $1800

Since I rounded down the initial car price, the correct answer would be a little more than $1800....

Final Answer: D

We are given that Mr. Goldstein negotiates a purchase price that is 20% less than $45,500.

Thus he pays:

0.8 x 45,500 = $36,400

Since tax is 5% of the purchase price, the amount of tax is:

36,400 x 0.05 = $1,820

Answer: D
