Explanation:

Step1: Find the change in price

The initial price is $0.20 per lb and the final price is $0.60 per lb. So the change in price is $0.60 - $0.20 = $0.40.

Step2: Calculate the rate of change

The time period is 4 years. The rate of change is the change in price divided by the time period. So, $\frac{0.40}{4} = 0.10$ dollars per pound per year.

Answer:

B. $0.10 per pound per year
