Question

You are an editor for your school yearbook. Each row of photos is 8 inches wide, including the two margins. Each photo is 1 inches wide, the space between each photo is inch, and each margin is inch. How many photos can fit in one row?

Answer 1

Given:

Width of each row of photos = 8 inch , includes 2 margins.

Width of each photo = 1 inch

Width of margin = 1 inch

Spacing between each photo = 1 inch

To Find:

How many photos can fit in one row.

Solution:

Its given that each row is 8 inch wide and it includes 2 margins.

We can imagine each row contains 8 boxes of 1 inch width.

• Width for each margin = 1 inch
• Width for 2 margins = 2 inch = 2 boxes filled.
• Number of boxes remaining = 8 - 2 = 6

Now we need 1 inch spacing between each photo.

If Number of photos = N ,

• The number of boxes for spacing = N-1
• As left side of first photo and right side of last photo will have margin.
• Therefore N + N -1 = 6
• 2N - 1 = 6
• 2N = 7/2
• N can be 3 or 4.

• if N = 4, the spacing will not satisfy as 4 photos take 4 boxes, spacing 3 boxes and margin 2 boxes which add up to 9 boxes.
• But we have only 8 boxes.

Hence,

The number of photos that can fit in one row is 3.
