Rate is an expression for a change of some unit per unit of time. For this problem, we find the rate of change of the price by a simple equation which is expressed as:

Rate = change in price / change in time

Rate = ($1.20/lb - $0.90/lb) / 5 yrs - 0

Rate = $0.06 per lb per year

Thus, the answer is B.
