A page of a school yearbook is 8 1/2 inches by 11 inches. The left and right margins are 1 inch and 2 1/2 inches respectively. The space between pictures is 1/4 inch. How wide can each picture be to fit 3 across the width of the page?

Subtract the two margins from 8.5 inches (8.5-3.5)=5 in
You now have 5 inches to fit in 3 pictures. The edge of the two outside pics fit against the margins. Draw 3 squares and the two small spaces b/t them are .25 each. There are 2 of them and that is .5 inches. Subtract .5 inches from 5 inches and get 4.5 inches. Divide the 4.5 inches by 3 and get 1.5 inches for each of the 3 pics.
2. equation: 8.5-(1+2.5)=5.0
5.0-.5=4.5
4.5 divided by 3=1.5

I don't have the exact equation, but would have to begin with 8 1/2 inches and subtract the margins, which total 3 1/2 inches. Right? We're down to 5 inches. Take away 1/2 inch (1/4 + 1/4 for the space between pics) and you get 4 1/2 inches. Now you have to divide that by 3. Draw a picture - that's a BIG help.

Width of page is 8½ in. Total margin space is 3½ in (1 + 2½).
To fit three pictures in the remaining space there is an extra space of 1in required for the spacing, that is ¼ in between the pictures and ¼ in to the left and right of the pictures (¼in x 4).
Page width - margin space - border space = 8½ - 3½ - 1 = 4 in.
So remaining space for three pictures is 4 in.
So space for one picture is 4/3 in.
P - Picture space.
Pw - Page width.
M - Margin space.
B - Border space.
3P = Pw - M - B
3P = 8½ - 3½ - 1
3P = 4in.
P = 4/3 in.
Each picture will need to be 1 1/3 in wide (that is 4/3 in).
These calculations include a picture space of ¼ in away from the margins.

width is 8.5
Minus left and right widths of 1 and 2.5 respectively.
So now we're working with 5 inches. We have 2 gaps of .25 inches so that's .5 inches less.
Now we have 4.5 inches. We want 3 pictures so we divide by three and get 1.5 inches each or 1 1/2 inches
