The rate of change can be calculated below
[tex]\begin{gathered} \text{rate = }\frac{\text{ number of potatoes}}{\text{plots}} \\ \text{rate}=\frac{60}{2}=30\text{ potatoes per plot} \\ \text{rate}=\frac{120}{4}=30\text{ potatoes per plot} \\ \text{rate}=\frac{240}{8}=\text{ }30\text{ potatoes per plot} \end{gathered}[/tex]
The answer is C. 30 potatoes per garden plot.
