Answer 2

Answer: $0.10 per lb per year

Given: The  price of bananas went from $0.20 per lb to $0.60 per lb in four years.

The change of price of bananas = $0.60-0.20=0.40$ per lb

Now, the rate of change of the price of bananas is given by :-

$\frac{\text{Change in price}}{\text{number of years}}$

$=\frac{0.40}{4}=0.10$

Hence, The rate of change of the price of bananas = $0.10 per lb per year
