This could include the extra labor involved in assembling a double patty burger, as well as the cost of the extra bun and condiments. Additionally, the pricing strategy may also take into account the perceived value of a larger, more substantial burger compared to two separate smaller ones. **

To calculate the storage space needed for 8000 photos and 789 regular videos totaling 84 GB, we need to determine the average size of each photo and video. If we assume each photo is around 5 MB and each video is around 100 MB, the total storage space required would be approximately 41 GB for photos (8000 photos x 5 MB) and 78.9 GB for videos (789 videos x 100 MB), totaling around 119.9 GB. This estimate allows for some variation in file sizes and metadata that may affect the overall storage space needed. **
