Final answer:
The percentage of decrease is 25%.
Step-by-step explanation:
To find the percentage of increase or decrease, we need to compare the original price and the new price. The original price is $10,599 and the new price is $8,000.
To calculate the percentage of increase or decrease, we need to find the difference between the new price and the original price, which is $10,599 - $8,000 = $2,599.
Next, we divide the difference by the original price and multiply by 100 to get the percentage. (2,599 / 10,599) * 100 = 24.51%. Rounding to the nearest whole percent, the percentage of decrease is 25%. Therefore, the correct answer is B) 25% decrease.
