The price of the blend ($5 per pound) is exactly in the middle of the prices of Kentucky bluegrass ($6 per pound) and ryegrass ($3 per pound). This means the blend should have equal amounts of Kentucky bluegrass and ryegrass to achieve the average price. Therefore, to mix with 180 pounds of bluegrass, 180 pounds of ryegrass are needed to get a blend that sells for $5 per pound. However, the correct answer is not listed, indicating a mistake in the question or answer choices. Given the options, none directly match the correct calculation based on the provided prices and desired blend price.
