Answer: $ 0.146 per year.
Step-by-step explanation:
Given: Average price of gas in 2000 = $1.57 per gallon
Average price of gas in 2005 = $2.30 per gallon
The rate of change for each year between 2000 to 2005
= [tex]\dfrac{\text{Change in price}}{\text{Change in time}}[/tex]
[tex]=\dfrac{\text{Price in 2005- Price in 2000}}{2005-2000}\\\\=\dfrac{2.30-1.57}{5}\\\\=\dfrac{0.73}{5}=0.146[/tex]
Hence, the rate of change for each year between 2000 to 2005 is $ 0.146 per year.
