Final answer:
After adding the 37 zoo pictures and the 25 museum pictures to get 62 and then subtracting the 29 deleted pictures, Robin has 33 pictures left from her vacation.
Step-by-step explanation:
Robin took a total number of pictures during her vacation by first adding the number of pictures taken at the zoo to the number taken at the museum. So, she took 37 pictures at the zoo and 25 pictures at the museum, which totals 37 + 25 = 62 pictures.
After her vacation, Robin decided to delete some of these pictures. The total number of pictures she deleted was 29. To find out how many pictures Robin still has, one must subtract the number of deleted pictures from the total number she initially had: 62 - 29 = 33 pictures.
Therefore, after deleting the unwanted pictures, Robin still has 33 vacation pictures.
