need to know how many photos will fit on one row in a School yearbook page

Question

1. You are the editor of your school’s yearbook. Each row of photos is 8 5/8 inches, including margins. Each photo is 1 ¼ inches wide, the space between the photos is 1/8 inch, and each margin is ¼ inch. How many photos can fit in one row?

Answer 1

Subtract the margins

8 5/8 - 1/2 = 8 1/8

p is the number of photos

p - 1 is the number of spaces between

 

8 1/8 ÷ (1.25p + 0.125(p - 1))

 

Can you solve for p and answer?
