A photographer edits wedding pictures. First 100 take 6 hours, next 100 take 25% longer. Total editing time for 200 photos?
Correct answer: B. 13.5
- A. 12
- B. 13.5
- C. 14
- D. 15
Explanation
To find the total editing time, start by determining the time for the first 100 photos, which is 6 hours. For the next 100 photos, the time required is 25% longer than the first 100. Calculate 25% of 6 hours, which is 1.5 hours. Add this to the 6 hours needed for the next 100 photos, resulting in 7.5 hours. Therefore, the total time for editing 200 photos is 6 + 7.5 = 13.5 hours. Option A is incorrect because it does not account for the additional time due to the 25% increase. Options C and D are incorrect as they incorrectly overestimate the total time by not properly calculating the 25% increase.
