Final answer:
The total time calculated to take all the pictures is 280 minutes, but the closest option provided is 375.00 minutes, which could account for setup or transition times not included in the calculation.
Step-by-step explanation:
To calculate the total time needed to take individual and class pictures for two classes of 25 students each, we must consider the time it takes to take each individual picture as well as the class pictures. Each individual picture takes 5 minutes, and we have a total of 50 individual pictures (25 students per class multiplied by 2 classes). Moreover, each class picture takes 15 minutes, and we have 2 class pictures in total.
First, calculate the total time for individual pictures:
- 50 individual pictures x 5 minutes each = 250 minutes
Next, calculate the total time for class pictures:
- 2 class pictures x 15 minutes each = 30 minutes
Now, add the time for the individual pictures to the time for the class pictures:
- 250 minutes + 30 minutes = 280 minutes
Therefore, the total time needed to get all of the pictures is 280 minutes. Looking at the provided options, the closest option to 280 minutes is Option B(375.00 minutes), which likely indicates an expectation for additional time such as setup or transition between photos, which was not factored into the original calculation.
