Apage in a photo album is 10inches wide by 12 inches tall. there is a 1-inch
margin around the page that cannot be used for pictures. the space between each
picture is at least 1/2 - inch. how many 3-inch tall pictures can you fit on the page in
one column? use a diagram to you solve the problem
10.

  3

Step-by-step explanation:

The diagram shows the 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.

answer:   14
