If seven equal-width panels have a combined width of 31 1/2 FT, what is the width of one panel?

If seven equal-width panels have a combined width of 31 1/2 FT, what is the width of one panel?

• A. 4 1/2 FT
• B. 4 FT
• C. 5 FT
• D. 3 3/4 FT

Answer: (A)

When panels are the same width, the total width is seven times the width of one panel, so you divide the total by seven. 31 1/2 FT divided by 7 equals 4 1/2 FT for each panel. This checks out because 4 1/2 FT times seven equals 31 1/2 FT. The other options don’t fit because they would produce totals of 28 FT, 35 FT, or 26 1/4 FT when multiplied by seven.
