Which option offers the lowest unit price?

• A. Two for $28 (unit price $14 each)
• B. One for $16 (unit price $16 each)
• C. Three for $42 (unit price $14 each)
• D. One for $12 (unit price $12 each)

Answer: (D)

Unit price tells you how much one item costs, so you can compare different deals fairly. Divide the total price by how many items you get:

• Two for $28 → $28 ÷ 2 = $14 per item

• One for $16 → $16 ÷ 1 = $16 per item

• Three for $42 → $42 ÷ 3 = $14 per item

• One for $12 → $12 ÷ 1 = $12 per item

The lowest unit price is $12 per item, which comes from the deal of one item for $12. That’s why this option offers the lowest unit price.
