Answer:
The Spotted Cows delivery service has a greater rate of change.
Explanation
The Spotted Cows function is: y = 2.8x + 2
Dairy Farms function is: y = 2.1x + 10
I have graphed these two functions to determine which has a greater rate of change. The red line represents the Spotted Cow service while the blue represents the Dairy Farms service. On the graph you can see that the red line intersects and shifts above the blue line, meaning the rate increases at a higher rate than the blue.
Hope this helps!
