Final answer:
The price per pound of the compost is $0.98.
Step-by-step explanation:
To find the price per pound of the compost, we need to divide the total cost by the weight. First, we need to convert two tons to pounds. Since there are 2,000 pounds in a ton, two tons is equal to 2,000 * 2 = 4,000 pounds.
Now, we can divide the total cost of $3,920 by the weight of 4,000 pounds:
Price per pound = Total cost / Weight
Price per pound = $3,920 / 4,000 pounds = $0.98 per pound
Therefore, the price per pound of the compost is $0.98, so the correct answer is a. $0.98.
