Answer 2

Answer: $0.10 per lb per year

Explanation:

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}}`

`=(0.40)/(4)=0.10`

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