Chain sells for $1.50 per foot. How many feet can you buy for $18?

• A. 24
• B. 15
• C. 12
• D. 18

Answer: (C)

This questions tests how to apply a unit price to a budget. Each foot costs $1.50, so the number of feet you can buy with $18 is 18 ÷ 1.50. That equals 12. You can also check by multiplication: 12 × 1.50 = 18, which matches your $18 budget. The other quantities would require more money (24 feet cost $36, 15 feet cost $22.50, 18 feet cost $27), so they don't fit within $18.
