A car salesman purchased a car at an auction for $8,550. he will re-sell the car at a markup of $11,970. what is the percent increase of the markup?

40%

Step-by-step explanation:

You subtract 11,970-8,550 = 3,420 to isolate the increase.

Divide 3,420/8,550 = .4 to get the percent increase of the markup.

The answer is .4 or 40% (they are equivalent)

You can check my work by multiplying 8,550 * .4 = 3,420

This answer is the percent of 8,550 that it increased (40% of 8,550) so make sure that is what the question is asking. If it is then it's your answer.
