Given:
The production on day 1 is 66.
The production on day 3 is 240.
We need to find the average rate of change in production from day 1 to day 3.
Consider the average rate of change formula.
[tex]\text{The average rate of change=}\frac{y_2-y_1}{x_2-x_1}[/tex][tex]\text{Substitute }y_2=240,y_1=66,x_2=3\text{ and }x_1=1\text{ in the formula.}[/tex]
[tex]\text{The average rate of change=}\frac{240-66}{3-1}=\frac{174}{2}=87[/tex]
Final answer:
[tex]\text{The average rate of change}=87[/tex]
