With special permission, the slope for a 6-inch building sewer may range from 1/4 inch per foot to 1/8 inch per foot. Which expression best describes this range?

With special permission, the slope for a 6-inch building sewer may range from 1/4 inch per foot to 1/8 inch per foot. Which expression best describes this range?

• A. 1/4 inch to 1/8 inch per foot
• B. 1/8 inch to 1/4 inch per foot
• C. 1/8 inch per foot
• D. 1/2 inch per foot

Answer: (A)

The range is described by its endpoints in a specific order: it can vary from 1/4 inch per foot down to 1/8 inch per foot. Writing the range as “1/4 inch to 1/8 inch per foot” keeps that start-to-end direction exactly as stated. It communicates the same bounds, just in the same sequence. Reversing the order would convey the numerical spread but not reflect the way the range is presented in the question.
