Answer:
James is wrong because if you increase something's price by 50%, and decrease it by 50% of the new price, it will be lower than the original price.
Step-by-step explanation:
Let's say that the computer's price is around $1,000.
Since we have to mark it up by 50%, we have to turn this into a decimal and multiply that decimal by the original price. Then add the product to the original price
0.5 x 1,000 = 500
500 + 1,000 = 1,500
The marked up price of the computer is $1,500, then reduce it by 50%, do the same process as the first step but don't add it to the original price this time.
0.5 x 1,500 = 750
The computer's final price is $750
