If 3 pounds costs $12.81, what is the unit rate per pound?

Explanation:
The main idea is finding the unit rate: how much one pound costs. Since $12.81 covers 3 pounds, divide the total by the number of pounds to get the price per pound. 12.81 ÷ 3 equals 4.27, so one pound costs $4.27. You can check by multiplying back: 4.27 × 3 = 12.81. So the unit rate per pound is $4.27.
