Answer :
Final answer:
The percentage change in the number of DVDs Mark has is 25%. This is calculated by finding the difference between the final and starting number, dividing that by the starting number and then multiplying by 100. This calculation results in a 25% change.
Explanation:
The subject matter of this query is the percentage change. To figure out the percentage change, you begin by calculating how much the quantity has altered, which in this case means subtracting the starting value from the final value. Therefore, Mark's DVD count has increased by 40 - 32 = 8 DVDs. Then, divide the alteration by the initial number and multiply by 100 to convert to a percentage. Therefore, the percentage change is (8/32) * 100 = 25%. So, answer choice (b) 25% is correct.

Answer: choice B 25%
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
Mark had 32 dvds now he has 40
