Answer:

3

Step-by-step explanation:

The diagram shows the answer: 3 pictures will fit vertically.

You can solve this algebraically as well. For n pictures, there will be n-1 spaces, so the total height of the page must satisfy ...

1 + 3n + 1/2(n -1) + 1 ≤ 12

3.5n + 1.5 ≤ 12 . . . . . . . . . . . simplify

3.5n ≤ 10.5 . . . . . . . . . . . . . .subtract 1.5

n ≤ 3 . . . . . . . . . . . . . . . . . . . divide by 3.5

Up to 3 pictures will fit in a column.
