The price of a computer was marked up by 50% and then marked down by 50%.

dalvyx [7]

Answer:

percent change = 25% (drop)

Step-by-step explanation:

James reasoning is incorrect

Let the original price of the computer = $1000

If the computer was marked up by 50% then 1000 x 1.5 = $1500

If the computer was then marked down by 50% then 1500 x 0.5 = $750

Percent change = [ (difference between final value and initial value) ÷ initial value] x 100

= [ (1000 - 750) ÷ 1000 ] x 100

= 25% (drop)
