If the list price of a new car was $12,300, what was the cost of the car to the dealer?
(1) The cost to the dealer was equal to 80 percent of the list price.
\(12,300 * 0.80 = $9,840\)
SUFFICIENT
(2) The car was sold for $11,070, which was 12.5 percent more than the cost to the dealer.
\(11,070 / 1.125 = $9,840\)
SUFFICIENT

Given: The list price of a new car was $12,300
Let x = the cost of the car to the dealer
Target question: What is the value of x?
Statement 1: The cost to the dealer was equal to 80 percent of the list price.
Rewrite as: cost to the dealer = 80% of list price
Substitute to get: x = 80% of $12,300
Since we COULD evaluate 80% of $12,300, we COULD find the value of x, which means we could answer the target question with certainty (but we'd never waste our time doing so on that day!)
Statement 1 is SUFFICIENT
Statement 2: The car was sold for $11,070, which was 12.5 percent more than the cost to the dealer
We can write: $11,070 = 12.5% more than the cost to the dealer
In other words: $11,070 = 12.5% more than x
In other words: $11,070 = x + (12.5% of x)
In other words: $11,070 = x + (0.125x)
In other words: $11,070 = 1.125x
Solve: x = 11,070/1.125
Since we can answer the target question with certainty, statement 2 is SUFFICIENT
Answer: D
Cheers,
Brent
