ExplanationThe question asks for a percent increase from the original price; be careful not to find 20% of $18,000, and reduce the higher total ($18,000) by that amount. Instead, you’ll need to find the amount that yields the higher total, when increased by 20%, though, it’s much easier to just increase the price in Quantity B and compare it to the total in the problem: 10% of $14,400 is $1,440, so 20% must be $2,880; adding this to the base price of $14,400 yields a total of $17,280. That’s smaller than what you were looking for, so Quantity A is greater.

Quantity B 
The base price of the car 
$14,400 
Let B = base price A car with all available options costs $18,000, an increase of 20% from the base price of the carIn other words, when we increase the base price by 20%, we get a new price of $18,000 Increasing a value by 20% is equivalent to multiplying that value by 1.20 So, we can write: 1.20B = $18,000 Divide both sides by 1.2 to get: B = $15,000 We get: Quantity A: $15,000 Quantity B: $14,400 Answer: A
