If 3 pounds cost $12.81, what is the total cost for 5 pounds?

Explanation:
Think in terms of price per unit. The total for 3 pounds is 12.81, so the price per pound is 12.81 ÷ 3 = 4.27 dollars. For 5 pounds, multiply by 5: 5 × 4.27 = 21.35. So the total cost is $21.35. The other options would require a different price per pound, which doesn’t match the given information.
